When Neil and Elizabeth take their children on a camping holiday to France, they find themselves continually bumping into over-friendly couple Simon and Linda. Elizabeth finds the couple weird, but when they begin to spot Simon and Linda's campervan in their rear view mirror, and a young boy goes missing from the campsite, they realise the couple are more than creepy....they're dangerous.
