Kirk is ordered to relinquish command of the Enterprise to Dr. Daystrom's new M-5 computer, which, according to Daystrom, can make all the decisions that a starship captain would encounter correctly and more quickly than any human. The Enterprise, with Kirk and a few others aboard, is engaged in Starfleet wargames, but the M-5 begins to treat the other ships as a serious threat and retaliates with full salvos of phasers and photon torpedoes, destroying one ship. Believing Kirk may have lost his mind, Starfleet gives the remaining ships permission to destroy the Enterprise.
