You get the ending you deserve.
When five friends inadvertently cause a deadly car accident, they cover up their involvement and make a pact to keep it a secret rather than face the consequences. A year later, their past comes back to haunt them and they're forced to confront a horrifying truth: someone knows what they did last summer…and is hell-bent on revenge.
