Chris (Steve Oram) and Tina (Alice Lowe) have headed off on a caravan holiday for a week, but Tina soon realises that Chris has been deliberately killing people they've met and making their deaths look like accidents. Despite initially being shocked, Tina's love for Chris means she eventually joins in the killings, enjoying the rush it gives here.
