A reluctant heroine is forced to suffer the consequences of a child's lie as her lover is put in jail for a crime he did not commit. In this classic British romance that spans several decades, Atonement (15), being shown at the Odeon, Cecilia's (Keira Knightley) fate is sealed on one lazy day on the family estate in 1935, when Cecilia's little sister Briony (Saoirse Ronan) sees her near-naked by a fountain with gardener Robbie (James McAvoy) .After a couple of miscommunications, Briony who is crucially described by Cecilia as "an unreliable witness", accuses Robbie of molesting her cousin. Cecilia is inconsolable, all at once realising her feelings for Robbie and watching as he's hauled away to jail. A few years later he's shipped off to war, still mourning what could have been. * The Weston & Somerset Mercury has teamed up with the Odeon, Weston, to offer two lucky readers the chance to win a pair of tickets to see a film of their choice, subject to availability.
