Charlie (Noel Clarke of STAR TREK INTO DARKNESS, DOCTOR WHO) and his friend, Mark, go to a storage facility. It's there they encounter Charlie's girlfriend, Shelley, who has recently left him. She's there with a few of her friends. Lots of bickering and bad feelings ensue.
Then, they call get locked into the facility after a airplane crashes near the facility. They do manage to get out and see that it may have been carrying something classified. Soon, people begin to die, killed by a large humanoid insect-like creature. Who will survive?
While the scenario is somewhat contrived (a bunch of people trapped together while something picks them off), the monster costume and effects are great. It sort of reminds me of the alien from the Predator movies. But what makes this movie is the ending, particularly the last shot, which reveals what's really doing on the entire time the story is happening. Recommended.
