Synopsis:
Diane Meade is assigned to be John Jones’ new partner. During a rescue of a trapped car, Jones disappears to become the Martian Manhunter. The Manhunter saves the car and then reverts to his Jones identity. Diane notices Jones’ absence and concludes John is the Martian Manhunter.

The next day a truck explodes. Diane asks John to become the Manhunter and save a nearby statue. Just then, a secretly constructed robot Martian Manhunter flys in to the rescue. With both John and the Manhunter seen at the same time, Diane gives up her suspicions.

A wanted crook named Willy Horan is spotted in the crowd. Jones tries to catch him but is shot. Jones continues on to catch the crook. Diane again suspects John of being the Manhunter. John pulls a metal charm from his pocket that apparently stopped the bullet. Diane is again fooled, but Jones must now be on constant guard.
