Sinopsis
El temperamental piloto Tuck Pendelton se presta voluntario para un experimento que consiste en miniaturizarle en el interior de una cápsula que debe ser introducida en un conejo. Pero unos delincuentes intentan apropiarse del invento, y Pendelton acaba por casualidad en el interior de Jack Putter, un ser humano hipocondríaco. A partir de ahí, ambos se verán obligados a colaborar para conseguir que Tuck pueda salir del cuerpo de Jack.
