He first appears taking the mutant squirrel with multiple eyes from the lake Homer polluted to the president who randomly chooses one of the options Cargill offers him. They cover Springfield with a large dome to contain the high levels of pollution, obviously outraging the citizens who formed as an angry mob to find and kill the Simpson family. Cargill discovers the Simpsons have escaped and becomes mad with power trying to trap them again. He then appears aiming a shotgun at Homer and Bart, yet when it's out to shoot them, Maggie throws a boulder on his head from behind, instantly knocking him unconcious. He is presumed to be arrested after the film's events.
