Henry Spivey is a middle-class efficiency expert living in a perfectly dull lifestyle in the suburbs with his wife, two kids, a dog, and a typical minivan.
Edward Albright is a top secret espionage agent trained to kill who speaks 13 languages, runs the mile in four minutes, and wields an array of high-tech weaponry and gadgets.
The two men have absolutely nothing in common.
Save for the fact that Henry is Edward and Edward is Henry. They are two personalities who happen to share the same body thanks to a special microchip implanted in their brain that make them the perfect secret agent who is actually unaware of his own cover identity and his own cover identity who can't possibly break his cover since he isn't even aware of it.
But when the microchip starts to malfunction, both alter egos find themselves switching roles to their mutual regret and in endangering their other lives.
