No Trace (1998)

This is a story of five friends in Reykjavik, Iceland: the swimming icon, his girlfriend, the sewage expert, the single mother and speed addict, and the convict. They throw a party, but the celebration goes too far, and the dead body of a young woman is the result. This is the beginning of a fast and ominous chain of events, which nobody could have anticipated and none of them are prepared for.
