Mario (Thomas G. Waites) and Luigi (Kurt Russell) run a plumbing company. Foreman Spike (David Clennon) was waiting for them to work for him. Mario didn't want to work with Spike because his father (Donald Moffat) is taking care of his sons. The shellcreepers (James Earl Jones), sidesteppers (James Earl Jones), and fighter files (James Earl Jones) are waiting for Mario and Luigi to fight them.
