Steve Beck works for Pat Garland, the crime boss of San Diego. Garland suspects a traitor in the organization, and sets Beck to ferret him out. Beck has five suspects—Sid Dominic, Eddie Cortes, Hervey Isham, Paul Moon and J. J. Everett. Each one holds a position of power, but only one is working for the Attorney General's office. Beck suspects Everett, Garland's lawyer. But Beck is also falling in love with Everett's 20-year-old daughter, Marcy, while at the same time trying to fend off the advances of Garland's wife, Lena. Torn between his allegiance and his heart, Beck finds he isn't as tough as he thinks he is—because whoever the informer turns out to be, it's still his job to kill him. And the weakest link in the organization is turning out to be Beck.
