Based on the book by Cecelia Ahern, 'PS, I Love You' stars Hilary Swank as Holly Kennedy, an American married to an Irishman called Gerry Kennedy, played by Gerry Butler. His death early on in the movie is not the last we see of him - in fact it's only the beginning. Initially Holly is utterly lost but soon she discovers that Gerry has planned ahead and written her a series of letters, which all seem to end with 'PS, I Love You'.
