Our take

Friends hide a deadly accident in this hook-handed slasher reboot. Rated MA 15+ for bloody horror violence, language throughout, some sexual content and brief drug use. Expect jump scares, stabbings, teen drinking and revenge-fueled kills.

Story (may spoil tone)

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.

Talk after watching

  • A cover-up haunts the group one year later. Why do secrets make people vulnerable?
  • The killer targets guilt, not random victims. How does accountability differ from revenge?
