8 Heads in a Duffel Bag

A mindless comedy.

This is a very black comedy. A mob courier is hired to transport the heads of eight murder victims to a mob boss. However, the duffel bag gets mixed up with the bag of a college student who is off on a vacation in Mexico with his girlfriend and her parents. However, the mother is a recovering alcoholic whom everyone believes is delusional when she claims to have found heads.
