Playing with overly potent self-made fireworks and Charlie's slingshot, Brad takes the blame when Charlie accidentally shoots April and is grounded as a result. On the roof that evening, Brad mistakes the Critters' crashing spaceship for a meteorite; Jay and Brad investigate and interrupt the creatures consuming a cow. The creatures thereafter kill and feed on a local police officer, and later besiege the farm and cut its electrical connection. While checking the circuit breaker, Jay is attacked by one of the Critters and, being severely wounded, just barely manages to escape.
