However, when the heart-stoppingly attractive Daisy walks in, Guy finds himself on a tour of coffee-shops, parks and banks - anything to see her again. This begins a hilarious rollercoaster that he finds himself unable to stop. The persistent 'Kathy' has him pencilled in for marriage, his laddish best mate starts dating his sensitive sister, his mother's health takes a turn for the worse and a sexy workmate has revenge on her mind. Even when progress is finally made with Daisy, he discovers her two kids and husband - who coincidentally wants to offer him a dream job. As he increasingly turns to the comforting climes of alcohol, the wheels threaten to come off and life seems to have one bad turn after another. However, with the help of Daisy, he begins to turn things around until a New Year's Eve party when the rollercoaster ride is finally turned upside down.
