Henry Spivey (Slater) is a middle-class efficiency expert living a humdrum life in the suburbs with his wife, Lily (Yara Martinez), their two kids, a dog, and a minivan. Edward Albright (Slater) is an operative who speaks 13 languages, runs a four-minute mile, and is trained to kill.
Edward works at Janus Headquarters. He was implanted with a chip that allowed his handlers to physically switch Albright's personality to that of his alias Henry, allowing him to lead a double life without either personality being aware of the other. However, there was a malfunction which caused Albright's personalities to switch at random, revealing his secret life to his alias. Henry and Edward are thrust into unfamiliar territory where each man is dangerously out of his element. Henry must learn how to be a super spy and Edward must learn to be a suburban family man. Both are in way over their heads and desperately try to avoid being killed.
