Clark has planned the perfect prom for his girlfriend Sharon. His plans are hijacked when Sharon invites her two best girlfriends, Neve and Heather, and their dates along on the perfect evening, but things only get worse. When all three are deserted by their dates at the beginning of prom, the trio go back out to their limo, where the driver has cleaned out the mini bar and takes them on a wild ride that lands them in a holding cell and ends with them crashing another school's prom.
