Ben and Julie's annual Halloween Party goes off the Richter scale when their single, high-maintenance friend drags in a homeless guy thinking he's a partygoer--because she needs an escort. Not only has she dated everyone there, but she doesn't know that Ben has invited her lame ex-boyfriend, hoping to reunite them. As she spends the night avoiding her ex, and the other undesirable guys in attendance, she interacts with a colorful assortment of party people. Between disappearing fortunetellers and overcrowded Jacuzzis, she questions whether real love is even possible. The irony: the only person she's the least bit attracted to is--the homeless guy.
