While she is fighting him off, the ship is raided and the passengers herded ashore. Eighteen months later Ann is celebrating her one year anniversary to Lawrence Reagan when her young sister-in-law announces she is in love, and it turns out to be Frank. Ann decides to save her husband's sister from a fate worse than death, and goes to Frank's apartment to prevent an elopement. Lawrence also goes to the apartment that night, and everyone is entangled in a crime of passion.
