We all have a great lost love. More than a year after their angry split, Ami meets hers, Ben, on a beautiful hillside by a tree - but he doesn’t remember her. A terrible car accident has robbed him of his memory. Of course Ami should tell him the truth but – recklessly, romantically – she seizes this second chance of happiness and we watch both relationships – before and after – cutting backwards and forwards in time, to find out what went wrong in the past, and what chance Ben and Ami may have of a happy ever after after all.
