Here's the synopsis:
Carter has hit rock bottom. In the space of a year he’s become homeless, single and unemployed in London. Life has been better. Carter wants to sort things out, starting with tracking down his elusive ex-girlfriend Kelly. It’s the 11 month anniversary of their break up, and now more than ever Carter feels that she is the key to restoring harmony to his life. Unfortunately Kelly has changed her number and he becomes determined to get her new one. A chance meeting on the tube with Kelly’s highly charged brother Aaron – a B-list American actor – provides just the opportunity Carter needs. But in return Aaron demands a favour of his own and Carter, desperate for the number he believes will prove his salvation, is sent on a mad trail around London, picking up a few unlikely accomplices along the way. Little does he know that his stumbling attempts towards reconciliation will take him on quite a different adventure. Could this be the opportunity Carter needs to regain control of his life?
