Sometime in the future, mankind has depleted all energy and fuel sources, however they have engineered a way to use human excrement as fuel.

After his best friend dies in an unexpected accident, black market dealer Young-gyu decides to wash his hands off his illegal activities and start a new life with his girlfriend Yu-ri. But his dream stalls when he learns that Yu-ri needs money for her father's surgery. To help her out, Young-gyu decides to do the job one last time.

Meanwhile, a married couple, Sang-ho and Chae-hee, boards Young-gyu's passenger boat heading to Weihai, China. That very evening, just when the boat enters international sea waters where countries' laws cannot be enforced, Chae-hee goes missing and all her pictures and belongings vanishes without a trace. Young-gyu finds Yu-ri on the same ship, and she claims to be the only witness to Chae-hee's disappearance.

At Sunjong University, a few students are serious, including Eun-hyo, who works hard at aerobics in hopes of doing well in a national competition. Most students goof off: drinking, partying, and focusing on sex. Eun-shik, a law student who's been in the military, is older but socially inept.

They begin an affair, leaving Eun-shik on the sidelines. The national competition approaches and complications arise.
