Warren Barrow writes mystery novels under a pseudonymn. He sends his publisher a series of tape recordings that appear to detail either the plot of his next mystery novel or the plan for a murder he is actually going to commit. Using his own name on the tapes, Barrow describes how he renewed a friendship with a very attractive girl named Janet West. Janey, however, is married and wants someone to kill her wealthy husband. Blinded by passion, Barrow agrees to commit murder. At the last minute, however, he gets cold feet and later, out of guilt, decides to kill Janet. The tape ends, however. The publisher and another writer, Tom Keller, become convinced that Barrow is planning murder. The publisher calls the police while Keller heads for Janet's apartment. At the apartment, Keller discovers Janet dead and Barrow holding the murder weapon. Barrow is taken to the police station where he provides an ending to his novel and a complete confession, all on tape.
