Lewisham. A Pupil Referral Unit. Two students – Desmond and Wiggy – are truanting their lessons. To distract themselves from the looming threat of their limited prospects post-education, they enact a series of daydream sequences which range from the naïve and fantastical to the bleakly familiar. When Wiggy professes the sinister power of the sea to consume ‘rotters’ like themselves, Desmond desperately utilises his strategies of escapism to combat his fear of the upcoming school trip to Southend beach.
