The episode opens with an advertisement for Slurm, a popular intergalactic beverage. The makers of Slurm are announcing a contest: Whoever finds a golden bottle cap inside a can of Slurm wins a free trip to the Slurm plant, a tour of the Slurm Factory, and a party with popular Slurm mascot Slurms McKenzie.
Fry resolves to find the bottle cap by drinking massive quantities of Slurm. Meanwhile,
Bender is sick with a high fever (900 °F);
Professor Farnsworth uses this as an excuse to test his experimental "F-ray", a flashlight-like device that enables the user to look through anything. He reveals that a watch that belongs to
Amy Wong, caught in one of Bender's cogs, is causing the fever. After repairing Bender, the Professor leaves the F-ray in the custody of Fry and Bender who use it to scan Slurm cans for the golden bottle cap. After checking "90,000" cans, they give up on finding the winning one. Fry settles in to relax with a Slurm and chokes on the winning bottle cap. The Planet Express crew arrives at the Slurm plant on Wormulon. After meeting Slurms McKenzie, they take a tour down a river of Slurm through the factory and see the Grunka-Lunkas manufacture Slurm. Fry tries to drink the Slurm from the river, but falls off the boat and does not know how to swim.
Leela dives in to save him, and Bender joins them, because "Everybody else was doing it." The three are sucked into a whirlpool and deposited in a cave under the factory. They discover that the factory they toured was a fake. They enter the real factory and discover Slurm's true nature: It is a secretion from a giant worm, the Slurm Queen. They are discovered and captured by the worms. Bender is placed into a machine designed to turn him into Slurm cans. Leela is lowered by crane into a vat of royal Slurm, which will turn her into a Slurm Queen. Fry is fed ultra-addictive "super-slurm" so that he cannot resist "eating until he explodes". Fry drags the tub of super-slurm to the crane controls so he can save Leela while continuing to drink. A freed Leela saves Bender slightly too late, leaving Bender with a hole through the side of his torso. Leela then saves Fry by dumping the super-slurm down a drainage grate. They escape, but are pursued by the Slurm Queen. Slurms McKenzie, exhausted from his years of partying, arrives and sacrifices himself to save Fry, Leela, his two supermodels, and Bender. When they escape, the Slurm Queen yells that the company is ruined by the discovery of the secret. Professor Farnsworth contacts a government agent to reveal the secret of Slurm. However, Fry is so addicted to Slurm that he tells the government agent that "grampa's making up crazy stories again" so it can continue to be produced. In the end, the entire Planet Express crew holds a toast to Slurms McKenzie and to Slurm. ==Broadcast and reception==
