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.
Each kind of scare is rated out of 10. Hover over a score, or use the info button, to see what it means.
5.2 out of 10,Strong
Blood, injuries and body horror shown on screen. Violence that happens off-screen barely counts.
Gore 5.2 is strong (5-6 on the scale):
4.1 out of 10,Moderate
Unsettling images, atmosphere and things that feel wrong. Not sudden shocks (Jumpscares) or waiting for something to happen (Suspense).
Creepy 4.1 is moderate (3-4 on the scale):
2.4 out of 10,Mild
Sudden shocks designed to make you jump, usually a fast movement or a loud noise. Not slow-building dread (Suspense).
Jumpscares 2.4 is mild (1-2 on the scale):
3.5 out of 10,Moderate
Tension and dread while you wait for something to happen. Not the scare itself when it arrives (Jumpscares or Gore).
Suspense 3.5 is moderate (3-4 on the scale):
2.2 out of 10,Mild
Horror that gets in your head: paranoia, madness, doubting what's real and ideas that stay with you. Not how a scene looks (Creepy) or feels in the moment (Suspense).
Psychological 2.2 is mild (1-2 on the scale):
Scare weighting compares each kind of scare with other films, lifting what's stronger than usual and lowering what's weaker, so only the strongest get near 10. The Scare Scale score is the average of the three highest.
