The much anticipated sequel to the 2005 girls vs. cave-dwellers hit The Descent will have its premiere in the UK in December before making its way to the U.S. in 2010. Directed by Jon Harris, the film sees the return of original cast members Shauna MacDonald, Natalie Jackson Mendoza, and MyAnna Buring.

The synopsis for The Descent 2 reads:

Traumatized, Sarah Carter (Shauna MacDonald) emerges alone from the cave system where she confronted her darkest dread. With no rational explanation to what happened, the authorities force her back into the subterranean depths to help locate her five missing girlfriends. But as the rescue party enters further uncharted domains, flashbacks start haunting Sarah as shocking memories of the past hit home. For they are venturing into the habitat of a new tribe of Crawlers, even more viciously feral than Sarah faced before.
