The Butterfly Effect

London bookstore owner William Thacker's quiet life turns upside down when a chance encounter with famous actress Anna Scott sparks an unlikely romance challenged by their vastly different worlds.

Unfounded suspicions lead a married couple to begin divorce proceedings, whereupon they start undermining each other's attempts to find new romance.

While visiting her father, an American teenage girl is thrown into London society during its final "Debutante Season."

Pushed to the breaking-up point after their latest 'why can't you do this one little thing for me?' argument, Brooke calls it quits with her boyfriend Gary. What follows is a hilarious series of remedies, war tactics, overtures and undermining tricks – all encouraged by the former couple's friends and confidantes …and the occasional total stranger! When neither ex is willing to move out of their shared apartment, the only solution is to continue living as hostile roommates until one of them reaches breaking point.
