A test pilot, Tuck Pendelton, volunteers in a top-secret experiment: he is to be shrunk and injected into a rabbit in a submersible pod. But at the moment of miniaturization, a group of Silicon Valley industrial spies break into the lab and steal one of the two microchips necessary for reversing the process. As for an amoeba-sized Tuck, he is accidentally injected into the body of an easily strung-out supermarket clerk, Jack Putter. As Tuck gets acquainted with Jack, the unlikely duo tries to retrieve the other chip, with the help of Tuck's estranged girlfriend, Lydia.
