While developing a powerful explosive, naval officer Paul Towne introduces his friend Richard Tracy to Judith Corbin, his friend since childhood. For years, Paul had assumed that he would marry Judith, but when Richard proposes, Judith, tired of waiting for Paul, accepts. Soon after the marriage, Richard becomes more interested in the new explosive than in his new wife, and to pay off gambling debts, he agrees to steal the formula and sell it to a foreign government.
