A family moves into a suburban house and, upon arriving at their new home, they start to suspect that they aren't alone, as a strange presence begins to manifest itself. Steven Soderbergh's first incursion into the supernatural horror genre, supported by a surprising script written by David Koepp (Stir of Echoes, Panic Room, Jurassic Park), which had its world premiere at the past edition of the Sundance Film Festival.
