Philomena is the true story of one mother's search for her lost son.

Falling pregnant as a teenager in Ireland in 1952, Philomena was sent to the convent of Roscrea to be looked after as a "fallen woman". When her baby was only a toddler, he was taken away by the nuns for adoption in America. Philomena spent the next fifty years searching for him in vain.

Then she met Martin Sixsmith, a world-weary political journalist who happened to be intrigued by her story. Together they set off for America on a journey that would not only reveal the extraordinary story of Philomena's son, but also create an unexpectedly close bond between them.

The film is a compelling narrative of human love and loss and ultimately celebrates life. It is both funny and sad and concerns two very different people, at different stages of their lives, who help each other and show that there is laughter even in the darkest places.
