Hwang Ji An is a successful 30 something year old shoe designer who ends up pregnant after a one night stand with the new office employee, Park Tae Kang.

Four guys with nothing better to do decide to rob a gas station. When they find out there isn't as much money as they expected, they lock up the employees and take over to make more money. They don't know how to run the gas pumps, and when the customers complain, the guys take them hostage. Everything is more or less under a chaotic kind of control, until they order Chinese food and make the mistake of harassing the delivery boy. He rounds up a bunch of other delivery boys to attack the gas station. Another confrontation with a high school gang and the local mafia provokes a bigger fight. Finally the police arrive for the final showdown.
