Glen Runciter runs a profitable business-deploying his groups of anti-psychics to commercial clients who would like privacy and security from psychic spies. However when he and his best group are ambushed with a rival, he’s gravely wounded and put into “halflife,” a dreamlike condition of suspended animation. Shortly, though, the surviving members from the team begin experiencing some unusual phenomena, such as for example Runciter’s face showing up on coins and the globe seeming to move backward with time. As consumables deteriorate and technology gets a lot more primitive, the group must find out what can be causing the shifts and what a mystical product known as Ubik is due to it all.
