With the prospect of another Christmas Day spent anaesthetised in front of the TV with his dear old mum, Harry is becoming desperate. For the next 80-odd minutes we watch his optimistic side try to convince his pessimistic side to take an active role in his own happiness, call people up – ex-girlfriends in particular - and get out. Optimistic Harry thinks the “disease” of loneliness can be beaten with outside help and a pint or two. Pessimistic Harry believes the problem is inside his head and that there’s no escape.
