Alan Groombridge is trapped. Husband to a woman he doesn't like, father to two children he never wanted, and manager of a tiny branch of the Anglian-Victoria bank, he is doomed to a life of domestic boredom and tedious routine. All that keeps him afloat is his one fantasy: stealing enough of the bank's money to allow him just one year of freedom - one year in which to live a different sort of life.

But one day the bank is robbed, the manager and cashier disappear and what was once a place of dull and dreary repetition becomes the scene of a brutal, chilling nightmare that might never end...
