After his impetuous musician girlfriend, Samantha, dies in an accident shortly after they had a fight (and nearly broke up), a grief-stricken British businessman, Ian Wyndham, living in London gets a chance to relive the day all over again, in the hope of changing the events that led up to her getting killed.

Will Freeman is a hip Londoner who one day realizes that his friends are all involved with the responsibilities of married life and that leaves him alone in the cold. Passing himself off as a single father, he starts to meet a string of single mums, confident in his ability to leave them behind when they start to ask for a commitment. But Will’s hope of a continued bachelorhood is interrupted when he meets 12-year old Marcus, in many ways his complete opposite.
