Taking a break from the search for their father, Sam and Dean head to Lake Manitoc in Wisconsin for a possible case. Three drownings have occurred there within a year, with the dead bodies mysteriously disappearing in the lake. The brothers soon come to believe that an avenging spirit of a young boy haunts the lake, and learn that the local sheriff (Daniel Hugh Kelly) and the father of the latest victim accidentally caused his death when they were children.

The brothers are asked by a man whom Dean and his father had previously rescued to investigate the mysterious crash of a commercial airplane that left only seven survivors, with signs pointing to a demonically-possessed passenger causing the accident. When they realize that the demon is now eliminating the survivors one by one, Dean is forced to face his fear of flying by following its next target (Jaime Ray Newman) aboard an airliner. He and Sam manage to get the demon into the galley on-board, but it flees its host during the exorcism. Despite this, they continue the ritual, sending the demon back to Hell.

When a man is killed—his eyeballs having exploded—after his daughter chants "Bloody Mary" three times in front of a mirror, Sam and Dean head to Toledo, Ohio, to investigate. They learn that Bloody Mary (Jovanna Huguet) is the ghost of a young woman who was murdered after her eyes were cut out, and her spirit trapped within the mirror that she died in front of. With the mirror now for sale in an antique store in the town, Bloody Mary has begun to target those nearby who secretly feel guilt over another's death. The brothers must find a way to stop her after a young girl (Marnette Patterson) inadvertently becomes her next target.

After Zach (Aleks Holtz), a college friend of Sam's, is arrested for murdering his girlfriend, the brothers head to St. Louis, Missouri, to investigate. Zach's sister Becky (Amy Grabow) claims that he was with her at the time of the murder, although security footage places him at the scene of the crime. After a similar murder occurs, they realize that the real culprit is a being with shape-shifting abilities. The shapeshifter then captures the two and plans to use Dean's form to kill Becky. The brothers escape and alert the police. Becky is saved, but the police believe Dean to be her attacker. As Dean later searches through the shape-shifter's lair, Sam visits Becky to make sure that she knows what they are dealing with. However, she reveals herself to be the shape-shifter and knocks Sam unconscious before morphing back into Dean.

Sam and Dean head to Ankeny, Iowa to investigate the brutal death of a college student, and the victim's girlfriend Lori (Jane McGregor) says that the attacker was invisible. More attacks occur, with the victims seemingly connected to the girl. The brothers believe that the killer is the Hook Man, and research indicates that it is the vengeful spirit of Jacob Karns, a preacher who murdered 13 prostitutes in 1862 with the hook that replaced his lost hand and was later put to death for his crimes. Despite the man being buried in an unmarked grave, Dean manages to locate it and burn his bones, but it has no effect. To stop the spirit, they must destroy the hook, which was reforged into an unknown object by the church after Karns' death. In order to be sure, they burn everything silver in the church, but it doesn't stop the Hook Man. Lori and the brothers are confronted by the Hook Man. As they fight him, Sam realizes that Lori's cross necklace—given to her by her reverend father—is made of silver, and the spirit vanishes once it is burned.

After a construction worker for a new housing development dies in a sinkhole, his brain dissolving within minutes, the brothers head to Oasis Plains, Oklahoma, to investigate. There they learn of mysterious, bug-related deaths in the town. After doing research, they discover that the land under development was the site of a Native-American settlement erased by US Cavalry massacres in the early 19th century and that the chief had laid a curse on the land as he died. Sam and Dean determine that the curse will reach its climax that night, and race to warn the family living there as swarms of insects attack. They are able to fight off the bugs and survive through the night, and the insects leave at sunrise. The site is shut down temporarily as the boys discovered an unmarked Native American grave and the developer, whose family they saved from the bugs, decides to make sure it remains shut down.

Though Missouri claims to have purified the house, Sam does not believe it was successful, so the brothers watch over the house. When the poltergeist returns, Sam's premonition starts to come true. The brothers rush in to rescue the family, but they themselves are saved by the spirit of their mother, who sacrifices herself to stop the poltergeist. Unknown to them, their father is at Missouri's house and though he dearly wants to see his children, he informs her that he can't until he knows the truth about something.

1x10 - Asylum

Sam and Dean receive a tip from their father, and travel to Rockford, Illinois, to investigate the haunted Roosevelt Asylum, where criminally insane patients rioted in 1964. One of the riot's victims was the chief psychiatrist (Norman Armour). The spirits there try to communicate rather than attack, leading the brothers to discover that the psychiatrist had been conducting cruel experiments on his patients like trepanation (it was implied that he was also practising it due to diagrams in the background and the belief at the time it could relieve cranial pressure) and others in order to test his theory that provoking extreme anger would be therapeutic for them. The ghost of the doctor then confronts Sam, causing him to lose his sanity and try to kill his brother. Dean manages to subdue Sam and burn the doctor's corpse, stopping the spirit and returning Sam to normal. In the end, Sam answers Dean's cellphone to find their father calling them.

John calls Sam and Dean, telling them he is hunting the thing that killed their mother and it is a demon. However, instead of letting them help, he tells them to investigate the disappearances of young couples in rural Burkittsville, Indiana, Sam reveals to Dean that he would rather track down their father, prompting the two to angrily separate. As Sam meets a fellow hitchhiker named Meg Masters (Nicki Aycox), Dean starts the investigation and saves a travelling couple from a living scarecrow. Dean calls Sam about the creature and discovers that a Vanir is being summoned in the form of a scarecrow to protect the town in exchange for annual sacrifices, with a sacred tree in the town giving it power. Because the couple intended for the ritual escaped, the townspeople choose Dean and Emily (Tania Saulnier)—a girl who lives in town with her aunt and uncle—to be the new sacrifices. However, Sam returns and rescues them, and the scarecrow instead takes Emily's aunt and uncle as its victims. The next morning, Emily and the brothers burn the sacred tree and then leave town. Meanwhile, Meg hitches a ride on the highway, but slits the driver's throat, collecting his blood into a goblet and using it to communicate with an unknown being whom she calls father.

At the congregation, Dean is chosen and is cured of his condition. However, he and Sam soon learn that an openly gay teacher died of a heart attack at the same moment that Dean was healed. Further research reveals that deaths occurred in unison with other healings, prompting the brothers to believe that the preacher is using black magic to control a Reaper; healing people in exchange for the lives of those he deems immoral. However, they eventually discover that his wife (Rebecca Jenkins) is behind everything, and rush to destroy the altar used to control the Reaper. The preacher begins to "heal" Layla (Julie Benz), a young woman with a brain tumour, and the Reaper then goes after Dean.

The brothers later discover that Cassie's mother (Kathleen Noone), a white woman, left her boyfriend, Cyrus, for Cassie's African-American father. Cyrus tried to kill him out of anger, but he gained the upper hand and ended up beating Cyrus to death, dumping Cyrus' body and truck in a nearby swamp. The boys assume that Cyrus' spirit has returned and is out for revenge against everyone connected to his death. They attempt to put Cyrus to rest by burning his remains in rusted out truck in the swamp. However, the ghostly truck appears and attempts to run Dean down, and they realize that Cyrus' evil personality had infected the truck, and led it to take on a life of its own. The brothers end up defeating it by having Dean lead it in a chase and tricking it into driving onto the hallowed ground of an old, burned down church causing the hallowed ground to destroy it.
