 In the definitively middle-class Royal Tunbridge Wells, 16 year old Lance has been romantically obsessed with Steph "the fittest thing since sliced fit" for exactly "3 years, 11 months and 25 and a half days". And he s barely even spoken to her. Unable to approach Steph, but desperate for something to change, Lance faces his worst fear - of holding  the worst party ever  when his parents go away for the weekend. Enlisting his enigmatic, porn-addicted best mate Henry to help plan things, Lance tries to work out what to do when "You ve got no girls, no idea and 24 hours to throw a party".
