Second trailer for Jon Harris' sequel to Neil Marshall's 2005 horror hit The Descent, aptly titled The Descent: Part 2.

Emerging from the cave system alone, distraught and covered in the blood of her missing companions, Sarah (Shauna Macdonald) is incoherent and half-wild with fear. Sceptical about her account of events and convinced Sarah's psychosis hides far darker secrets, Sheriff Vaines (Gavan O’Herlihy) doesn’t waste time. Along with his partner Rios (Krysten Cummings), and their cave rescue team Dan (Douglas Hodge), Greg (Joshua Dallas), and Cath (Anna Skellern), Vaines forces Sarah back into the caves to help the rescuers find her friends.
