Synopsis:
Peacemaker has captured Andre Pierre Mazarin, a leader in the conspiracy to assassinate scientists. However, the assassin named Flowers has already been dispatched to murder Checkmate scientist Professor Braddock. Bishop is also after Braddock. Flowers, Bishop, and Peacemaker all arrive at Braddock's home at the same time. Peacemaker assumes that Bishop is the killer and starts fighting him. This allows Flowers to escapes. Checkmate agents then arrive including Winston, who was suspected of being Bishop. Winston fights Bishop and finally unmasks him as Checkmate knight gone bad Jacques Reynard.
