In a house balanced on an eroding cliff in North Norfolk, Manny gets a surprise visit from his estranged sister, Jessie. Inexplicably, she’s brought along a petty criminal, Lee Farrier, trussed in a sack. As a rising tide eats away at the foundations, a local girl, Cally, arrives, prompting all four to admit what’s really brought them together, the lies they’ve told, and the strangely redemptive power that might just be buried beneath their feet.
