While waiting at the Bikini Bottom Dock & Shipyard, SpongeBob prepares for summer camp at Sun Fun Island. All of a sudden, Patrick comes running to SpongeBob mentioning to him that he never told Patrick that he was leaving. They both were crying and hugging each other as the other campers went to Sun Fun Island and the Inferno Island boat appears. SpongeBob planned Patrick to come to camp with him not knowing they are going to prison camp. SpongeBob did not know about the camp so well, he thought Sun Fun Island was boring.
The warden greeted the prisoners to Inferno Island, but got assaulted through the sound of cheering from SpongeBob and Patrick. The warden even got annoyed when SpongeBob whispered to Patrick that he felt like eating him (not literally). Patrick felt kind of hungry when the warden mentioned it and he gave SpongeBob and Patrick tires to eat. The warden and the others were assumed about both of them eating the tires. The warden had SpongeBob and Patrick digest the tires in a low, narrow hole with chum buried on top of them.
Three days later, the warden lets SpongeBob and Patrick out of the hole, but they did not felt punished since they thought it was an enjoyable soap. The warden felt so ashamed that he made the activities very boring and difficult. Apparently, SpongeBob and Patrick thought that the "Coal Breaking" activity was fun and challenging even though they were wearing heavy ankle weights.
SpongeBob comes to the conclusion that Patrick and him are having more fun than the other prisoners. Patrick suggests that they do a fun activity altogether, then they would be having the same amount of fun as each other. This hatches an idea in SpongeBob's brain, so he works on a play all night. The warden finds the script and in the morning yells at the prisoners to find out which one of them wrote the paper. SpongeBob speaks out and says it was a play for "amusement and inspiration."
SpongeBob builds a boat for the play to take place in. One of the prisoners notices that they could use the boat to escape. After the play, the prisoners attempt to escape from the island, until they realize that the boat is just a prop and is not real, leading them to sink. The prisoners swim back to the island, and the warden is now furious. Suddenly, the Counselor of SpongeBob's camp comes to Inferno Island, to retrieve SpongeBob, who was absent from his camp. The prisoners, seeing their chance, all say that they are SpongeBob so they can be taken to Sun Fun Island. The warden asks the counselor what kind of activities they do at his Sun-N-Fun Island. The counselor says that they make macaroni art, sing campfire songs, and help and support each other.
So, at the end, the inmates, prisoners, and SpongeBob and Patrick make macaroni art. Patrick confesses that he likes the other island better and so does SpongeBob, with the two still oblivious to the truth.
