The episode begins as Dr. Venture and Brock are in the Venture Compound hangar, renovating an excavation vehicle left behind by Jonas Venture Senior. While Brock is driving the vehicle out of a garage, Dr. Venture falls through a pair of ancient doors, which the vehicle then falls partly into. Topside, the vehicle has completely blocked any access below, so Brock descends through a nearby door, which is nearly rusted shut. Meanwhile, Brock and Dr. Entmann present M.U.T.H.E.R. with Dr. Venture Senior — as best they can — by playing the personal hygiene punchcard lesson for her.
