Damon and Debbie squat on a boat moored on the River Ouse in York, where Debbie hopes to go to university and Damon plans to start his own business, but the boat's owner sails away with all of their belongings, including Debbie's insulin.

The couple visit Morecambe, then move to Bradford to stay with friends. Debbie, who has kept her diabetes secret from Damon, tries to locate a pharmacy to obtain insulin.

When Damon catches Debbie injecting herself, he wrongly assumes she is a heroin addict. Back in York, after the couple enjoy a mock wedding, tragedy strikes.
