Danger Force and Captain Man go undercover as bad guys at The Beatin' Dungeon to catch a criminal. If their cover is blown, they'll have to fight all of Swellview's toughest villains at once.

A gas leak forces Swellview to quarantine and Captain Man and Danger Force are forced to stay in their homes to set an example. But when Captain Man gets a little cabin fever, nothing will stop him from finding out who caused the leakage.
