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. One year later, the past comes back to haunt them as they learn someone knows what they did last summer. Stalked by a mysterious killer, they soon seek help from two survivors of the legendary Southport massacre of 1997.
