Brookside meets The Crazies in this inventive low-budget British feat­ure. When a mysterious container washes up on a Wirral beach, an ordinary cul-de-sac gets locked-down by a Special Ops team and the locals worry about the unknown threat – could it be Islamist terrorists at No 22? Curtain-twitching soon reveals something even more horrible – but it’s really only the first half hour of this film, with its nicely drawn, not entirely sympathetic characters and growing sense of panic that delivers the goods; the remainder is frittered away on ever-increasing histrionics and people running about covered in blood. The film never succ­eeds in uniting its two plot strands, one a sub-X-Files horror yarn, the other a soapy tale of a mother alienated from her daughter. A brave, bloody and well executed stab at something more ambitious than the average Brit horror, but a wasted opportunity.
