Unhappy with the Springfield Nuclear Power Plant's new exercise program, Homer decides to get on workman's comp by purposely gaining 61 pounds. He succeeds in his goal and is able to work at home. He spends a lot of his time goofing off and tries to go see a movie. When he is turned away because of his weight, Homer returns home but finds that a nuclear meltdown is about to take place at the plant. He hijacks an ice cream truck and rushes to the plant and is able to save everyone when he falls into a tank and prevents poisonous gas from escaping. As a reward, Mr. Burns guarantees to make Homer thin again, but gives up and decides to pay for a liposuction.
