Backpacker Cassie (Ricci) is headed for the English village of Ashby Wake when she's hit by a car. The driver, Marion Kirkman (Fox), takes Cassie to her house to recover since she's lost her memory. Marion's husband Simon (Dillane) is researching a recently uncovered first-century church with some unusual iconography that's drawing a number of strangers to the site. Cassie begins to have premonitions about the Kirkmans and the church and her possible ties to the mystery.
