In 1977, NASA launches a probe containing four hamsters to destroy a mysterious mass of radioactive cosmic Jello that was nearing Earth. Exposure to the substance mutates and anthropomorphizes the hamsters. Their vessel later crashes down near a Tibetan monastery, where they are adopted by the monks, trained in the martial arts, and named after famous martial arts and action-movie actors (Clint Eastwood, Jackie Chan, Bruce Lee, and Chuck Norris).
