Meanwhile, in the vivarium, some of the chimps have unlocked their cages and have stacked crates and boxes to attempt escape through a skylight. Jimmy and Teri walk in to see the chimps escaping. Virgil, at the top of the stack, is about to break the skylight with a crowbar when the authorities enter. Goliath the chimp becomes very angry and fights with Dr. Carroll. The authorities are chased from the room, and Goliath and Virgil end up in the flight simulator room. A jammed fire extinguisher moves the radiation generator into an exposed condition, potentially leading to an uncontrolled radiation blast. Jimmy gets Virgil and some other chimps out, but Goliath continues smashing the simulator and is caught inside. Jimmy and Virgil convince Goliath to yank out the extinguisher, but Goliath dies from radiation.
