The Test of Manhood.

Harry Wentworth is the profligate son of a ranch owner. His father is tired of Harry's irresponsible drinking and gambling and banishes him from home. Harry becomes a sailor, but right away gets in trouble with the captain. The hard work does him good, however, and when he feels he's had enough of the captain's brutality, he escapes overboard with a couple of friends, whom he takes to his father's ranch. Back home he discovers that his father is in danger of losing his ranch to scheming lawyer Jim Martin. Martin is in love with Ethel Crandall, the sister of gambler Ralph Crandall.
