Soft Boiled (Tempered Steel)

John Steele (Frank Beal), a rich uncle, threatens to disinherit his nephew, Tom Steele (Tom Mix), unless the latter learns to curb his violent temper. Tom is put on a 30-day trial and must resist all temptation to get mad or fight back no matter how provoked. And he is easily provoked, especially when called a lavender sissy-boy.
