Toughened criminal Jim Reagan tries to persuade his brother, Larry, to go straight, but Larry attempts to rob a banker, Richard Milton, and is arrested. Milton refuses to be lenient, and when Larry is killed trying to escape from prison, Jim and his wife, Molly, resolve to have vengeance. Through spiritualism they dupe Milton into contributing large sums to charity, then kidnap Milton's daughter, Nadine, after rescuing her from a shipwreck. Molly softens, however, returns Nadine to her father and, although Jim is at first enraged, finally persuades him to reform.
