Living a desultory existence clerking in an Ireland pet shop, troubled Yank ex-pat Mina (Dakota Fanning) is tasked with delivering a rare bird to a Belfast zoo. The car trip finds her broken down deep in uncharted woodlands, and stumbling upon a lone bunker... whose trio of occupants (Olwen Fouéré, Georgina Campbell, Oliver Finnegan) apprise her that she's found the only safe haven from predatory creatures that emerge at night. Unnerving bow for director Ishana Shyamalan co-stars Alistair Brammer
