British supernatural horror. Harry Treadaway stars as Matthew Ryan, a young Londoner whose life has been devastated by the disappearance of his younger brother, Tom (Lewis Lemperuer Palmer). His father Jake (Greg Wise) had entrusted Tom to Matthew's care, and Matthew is weighed down with responsibility and guilt. When he hears his brother's voice on a tape begging for help, he suspects he is going mad - but his neighbour Amy (Ros Leeming) convinces him to visit a medium and discover the true source of the ghostly voice he is hearing. But as the haunting continues and the mystery deepens, Matthew realises that it is impossible to bury the past.
