The X-Files' Gillian Anderson gives an impressive performance as a woman obsessed by revenge in this sleek and chilly English thriller by documentary filmmaker Dan Reed. Anderson is top-billed as a Brit businesswoman who invites the rough-hewn tech (Danny Dyer) who's installing her security system to a business party in the country. Slow-boiling sexual tension between the two to an erotic encounter in the woods - which is soon undercut by a savage attack by a group of local hunters, who rape Anderson and beat Dyer senseless. As they recover, viewers soon learn that the pair's trauma runs deeper than just the physical level - Dyer is emotionally shattered, and Anderson is gripped by a need to repay her attackers with violence more terrible than what they visited upon her. Though the plot occasionally veers into implausible territory, the couple's search for the guilty party - and the gruesome fate they have in store for them - is unnerving, and made all the more so by Anderson intense turn, which presents a torrent of conflicting emotions raging just below her cool, porcelain surface. - Paul Gaita
