Rhesus 2 plants a psycho-neutron annihilator bomb on the Primate Avenger, probably the worst kind of neutron annihilator there is! The bomb can destroy all life forms, and projects illusions to protect itself from being discovered. The monkeys must conquer monsters drawn from their own deepest fears if they are to find the bomb, save the ship and get back to that game of Holo-Chess!
