Pilot Episode: Working out of a patrol car designated "Adam-12," Officers Malloy and Reed perform a typical day's work, which includes a high speed auto-chase, the capture of two robbers, and an emergency call to save a suffocating baby. Malloy decides to turn in his badge after his young partner was killed a few weeks earlier. But at the end of the shift, he comes around and decides that he can't let inexperienced Jim Reed loose on another officer, so he decides not to leave the force.
