Security guards Chuck and Bobby play a game of Red light/Green light while being night watchmen for Howard County Bank and Trust and are obsessed with elaborate schemes of would-be thieves. They hear a sound coming from a floor polisher that Ernest (who works as a night custodian but dreams of being a clerk) is trying to turn on for operation, but he ends up making a mess in the bank and he becomes magnetic from a mishap with the floor polisher. The next day, World bank Oscar Pendlesmythe's assistant, Charlotte Sparrow orders him to clean up his supernatural mess. Pendlesmythe wants to terminate Ernest's employment at the bank, but Charlotte has a soft heart for misfits and stray dogs, so she argues on his behalf. Ernest takes a bath at home in a tumble dry washing machine and uses a blow dryer with a windtunnel force for his evening dinner with Charlotte in a restaurant. He later receives in the mail a summons stating that he has been selected for jury duty in court and tells the two watchmen about it. During the trial, Dracup Maximum Security Prison convict and defendant Rubin Bartlett notices that Ernest is a dead ringer for death row inmate Felix Nash. Bartlett has his lawyer convince the jury to tour the prison, where Bartlett arranges for Ernest to be kidnapped by Nash and another inmate named Lyle and switched with Nash. After the jury returns to court, Nash tricks the jury into announcing Bartlett not guilty, allowing Bartlett to return to jail and resume his current sentence. Even though Ernest tries to tell the guards he is not Nash, they refuse to believe him. Ernest also does not know that he has a death sentence, which is for Nash.
