Hush (2009)

Mark Tonderai's Film4-funded thriller stars William Ash and Christine Bottomley as Zakes and Beth, a couple whose relationship is failing. Although he's an aspiring writer, he is resigned to a job replacing posters at petrol stations, and one night Beth accompanies him. Zakes accidentally cuts up a white van, which pursues him; as it violently overtakes them, the back door swings open and Zakes glimpses a naked woman chained up in the back, before the door swings shut and the truck disappears. Zakes becomes fixated with tracking it down but at the next service station, Beth storms off. When she doesn't return, Zakes discovers she has been snatched by the van driver and finds himself drawn into a deadly and gory cat-and-mouse game against the driver and his sinister accomplices.
