This movie filled me with a sense of dread from the get-go.

A couple travels to a remote lake with plans of romance and marriage proposal. But when a group of teen hooligans crash the party, things go tragically and horribly wrong.

The only real "spoiler" in my review is that children will learn the bulk of their behaviors from their parents. And the ending holds true. You can almost tell which adult is the parent of which of the hooligans as the final scenes play out.
