Wilson (Natalie Moorhead) is a gold digger and black mailer who gets involved with older rich married men and then threatens to wreck their families by telling about untrue affairs if they don't pay up.
Businessman John Randolph is one such victim, but his wife wants to leave him already. The son, Richard (Jack Mulhall) persuades his mum to stay as dad is innocent and then he goes in pursuit of Wilson on an ocean voyage. He decides to pose as another sucker to prove Wilson's scheme...
So, naturally the story has a simple idea with various layers of complexity and characters of varying importance laid on. The film is difficult to get going but is fair enough when the voyage is progressing and does indeed have an exciting conclusion.
