The latest film from award-winning theatre and film director Richard Eyre (Notes on a Scandal, Iris) is part love-story, part thriller, based on a short story by Bernhard Schlink. Peter (Liam Neeson), the CEO of a computer software company, has been married to Lisa (Laura Linney), a successful shoe designer, for well over 20 years.

Her work means frequent travel, but their marriage seems happy, and they have a grown up daughter, Abigail (Romola Garai).

Missing his wife, Peter discovers that she has been receiving emails and messages from a man he never knew existed.

Against Abigail's advice, feeling betrayed and vengeful, Peter flies to Milan to find out the truth about the mysterious other man, Ralph (Antonio Banderas). As Peter begins to unravel his wife's secret, the focus shifts to a suspenseful cat and mouse relationship between the two men.

Once again, Richard Eyre demonstrates his skill in capturing the subtle nuances of love, betrayal and forgiveness, in a story which explores how well we can ever know the people that we love.

Starring: Liam Neeson, Antonio Banderas, Laura Linney, Romola Garai
