It's Jeff Chang's 21st birthday, so his friends, Miller and Casey show up to help him celebrate. But Jeff has an interview the next day for medical school which his very strict father is going to bring him to, so he can't go out. But Miller convinces Jeff to go out and they get so drunk that they don't know where they are and how to get back Jeff's place. So they try to ask a girl whom Jeff knows if she could help them but she doesn't know either. But she tells them maybe her boyfriend might know. So they go to him but problem is that the guy is someone they met during their binge and all he wants to do is kill them so they run off. And they try to find Jeff's place before his father shows up and kills them.
