A Navy test pilot is shrunk in a ground-breaking scientific experiment, but instead of being injected into a laboratory rabbit, the tiny specimen accidentally winds up inside a hypochondriac supermarket worker. As he tries to find a way out, criminals come after the unlikely duo in search of the secret of the miniaturising technology. Sci-fi comedy, starring Dennis Quaid, Martin Short, Meg Ryan, Kevin McCarthy, Fiona Lewis and Vernon Wells.
