Peter Beaupre, Alice Ribbons, Burton Jernigan, and Earl Unger are four internationally wanted hitmen working for a North Korea terrorist organization. Having stolen a US$10 million missile-cloaking computer chip, the thieves put it inside a remote control car to sneak it past security at San Francisco International Airport. However, a luggage mix-up occurs, causing a woman named Mrs. Hess to inadvertently take the thieves' bag containing the car, while returning home to Chicago. The four thieves arrive in Chicago and systematically search every house in Hess's suburban neighborhood to find the chip.
