Hi, I am desperatly trying to remember the name of a movie from the 1980/1990's. Its American.

It's about a group of college boys who think they kill a girl at a party. They bury her. Years later when they are adults they have to get back together to dig her up as its being excavated.

One of the men had actually played a trick on them and the girl they thought they killed wasn't dead and they buried a mannequin. He wanted them to help move the body. The others don't want to and end up killing him then find out it was all a joke.

Several times throughout the movie they call ollie ollie oxen free, can't remember why. Hope this is enough info it is driving me crazy.

Thanks heaps
