Golddigging Verna Wilson (Natalie Morehead) files suit against married millionaire John Randolph (Montague Love) for breach of promise. On the verge of collecting $100,000 in "hush money," Verna discovers that her former lover (Roy D'Arcy) has broken out of jail and is heading after her with blood in his eye. Frantically, she books passage on an ocean liner bound for Europe. During the voyage, Verna is confronted by another man -- Dick Randolph (Jack Mulhall), son of the disgraced millionaire. Not long afterward, Verna's ex-lover catches up with her . . . and the result, inevitably is murder. But who done it (and who is it "done" to?) Love Bound was also released as Murder on the High Seas and Souls for Sale.
