Shauna Macdonald (Mutant Chronicles, The Descent) returns as Sarah, continuing the story of 2005’s hugely successful horror thriller The Descent, in which a group of young women disappear during a caving trip in the Appalachian Mountains.

Emerging from the cave system alone, distraught and covered in the blood of her missing companions, Sarah 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.

Alongside Macdonald, The Descent: Part 2 also features Natalie Mendoza reprising her role as Juno. Krysten Cummings, Anna Skellern, Gavan O’Herlihy (Seven Days of Grace), Joshua Dallas (Ghost Machine, “Doctor Who”) and Douglas Hodge (Mansfield Park) also star.

The Descent: Part 2 is written by James McCarthy, J. Blakeson and James Watkins (Eden Lake). The film is produced by Academy Award® winner Christian Colson (Slumdog Millionaire) and Ivana Mackinnon (The Scouting Book for Boys). Neil Marshall who directed the original film serves as executive producer with Paul Smith (The Descent, Slumdog Millionaire). Previously a well-known editor on films including Kick-Ass, Eden Lake, Stardust and Layer Cake, as well as The Descent; Jon Harris makes his debut as director.
