Disturbing secrets lie buried in the bogs of a remote island in this spellbinding thriller. Shortly after surgeon Tora Hamilton (Radha Mitchell) moves with her husband (Rupert Graves) to the Shetland Islands – 100 miles off the coast of Scotland – she makes an unnerving discovery: the body of a young woman with strange symbols carved into her flesh and her heart ripped out. When what at first appears to be the remains of a victim of an ancient ritual turns out to be a fresh corpse, Tora is plunged into a dangerous mystery that may be connected to the dark myths of the island’s folklore.
