Plot?

Overall, a guy tries to find out some more about his past, as he knows he is adopted. He gets a key from his brother, a key from a storage facility. There he finds a box, with some newspaper articles and some videos of his real family. Also, later one, he finds, someone, who is also in her own personal search. The storage is over an old asylum, so it is safe to assume that the person haunting them is not in heir right mind. One night, he and some new found friends get locked in, and the killings begin.
Found it to be interesting, considering the budget, the way it was executed and the place picked.
More mystery, tho not too hard to predict it, but overall a good movie considering all of the above.
