Summer Heat (Dutch: Zomerhitte) is a 2008 film directed by Monique van de Ven.

Photographer Bob Griffioen (Waldemar Torenstra) is in Afghanistan with his girlfriend when they witness rebels attacking a car.

The beach appears to be deserted, until he sees the naked Kathleen (Sophie Hilbrand) emerging from the sea.

Kathleen is paid by an older man (who we later discover belongs to a drug gang) for allowing him to watch her fingering herself.

Bob throws him into a shallow lake in the dunes, with a heavy bag with drugs strapped to his body to keep him underwater.
