SpongeBob and Patrick are at the movie theater going to see Fisherman 4: Attack of the Hook. They meet Squidward who laughs saying they won't sleep a wink after seeing the movie. They both claim they're grown-up men, but Squidward says "Boo" in monotone and scares them effortlessly. Then they decide that they'll show Squidward that they are not afraid of Fisherman: 4 Attack of the Hook. They go and see the movie, and are instantly scared. They try not to look at the movie, but it is over when they open their eyes. They stay for the second showing to try to keep their eyes open, but they fail again. When they get out, they realize that it is midnight, the time when the Fisherman strikes. While walking home, they repeatedly mistake him for shadows of harmless beings. They eventually get home, but they are too scared to walk to their houses by themselves. They get so scared, they woke Squidward up. Squidward gets annoyed by this, so he carries them to their houses. Even after they get home, they yell back and forth between their houses, which annoys Squidward even more. Squidward then decides to disguise as The Fisherman to scare SpongeBob and Patrick. He hooks Patrick, who runs screaming into SpongeBob's house. He tells SpongeBob about the Fisherman (who is really Squidward), and they become even more scared. They board up the door to SpongeBob's bedroom, but Squidward enters through the window anyway. SpongeBob and Patrick are scared out of their wits, and exchange each other's underwear so they don't die in their own. While SpongeBob and Patrick are screaming, Squidward's head comes out of his disguise, while laughing, which SpongeBob and Patrick mistake as the Fisherman eating Squidward. They attack Squidward, attempting to save him. They throw him out of the window and Patrick then flings objects on Squidward, leaving him in a coma. An ambulance comes to get Squidward, who is badly injured while SpongeBob and Patrick are glad now that they don't have to worry about the Fisherman anymore. Then the Fisherman costume rises up and roars, this time without Squidward. SpongeBob and Patrick get scared out of their minds and go in the ambulance with Squidward, only for The Fisherman costume to fall, revealing Gary.
