Michael Lanyard, a reformed cracks-man, adopts Adrienne, the daughter of an old friend, and goes to Southampton to attend a party celebrating her engagement to Bobby Crenshaw, the son of a wealthy society couple. The Count and Countess Polinac, international jewel thieves, also attend the party, and Count Polinac forces Lanyard to open the safe containing the jewelry of the guests by threatening to expose Lanyard's criminal past. Lanyard forestalls the count, however, and protects the valuables. The count and countess are arrested, and Michael's secret is kept safe.
