the decent movie trailer

Holly falls down a hole and breaks her leg. Sam sets Holly's fracture with a splint and they carry her. As the others help Holly, Sarah wanders off and observes a pale, humanoid creature drinking at a pool. It scampers off into the darkness when Sarah gasps. The others think Sarah imagined it, but Sarah insists that she saw someone. Soon after they are attacked by one of the creatures, referred to as "crawlers". The group scatter, and the crawler rips Holly's throat. Sarah trips and falls and passes out. Seeing Holly is still alive, Juno tries to defend the decent  her from the crawlers, but in the confusion, she whirls around, only to stab Beth through the neck with her pickaxe. Beth grabs Juno's pendant as she drops to the ground, but Juno stumbles away in shock as Beth reaches out to her. Juno eventually locates Sam and Rebecca and rescues them from a crawler. Juno tells them she may have found a way out, but will not leave without Sarah. The others reluctantly agree to help her search. Meanwhile, Sarah awakens and encounters the mortally wounded Beth, who tells Sarah that Juno wounded her and left her. Sarah does not believe her until Beth gives her Juno's pendant, which is inscribed with the words "love each day." Beth, in extreme pain, asks Sarah to euthanise her, and Sarah reluctantly complies. Sarah soon encounters and kills a young crawler, a female crawler, and a male crawler in quick succession. Elsewhere, Juno, Sam and Rebecca are pursued by a large group of crawlers. Crawlers kill Sam and Rebecca, and Juno leaps into a chasm to escape. watch more
