Officers Malloy (Martin Milner) and Reed (Kent McCord) swing into action when suspicions arise that a hit-and-run accident was actually a case of cold-blooded murderer. Witnesses insist that a young man had a violent quarrel with the female "accident" victim on the night before the tragedy. The guest cast on this occasion includes several reliable character actors, including veteran vaudevillian and master dialectician Benny Rubin. ~ Hal Erickson, Rovi
