Hamish enjoys re-acquainting himself with the island and he's delighted when Douglas finds the fishing boat he used as a kid. It ushers in warm memories of his own childhood. The boat is almost seaworthy, but it just needs a little work to prevent any leakage, which Robbie is happy to undertake.
Kenny is preparing Abby, and in a subtle way, the kids, that it's time he left the island for good. She knows he finally has to move on, but she can't allow herself to loan him the money he needs to return to London. That night Kenny boards Hamish's boat to mount a salmon rescue mission of his own - maybe he can make a few quid on the catch. But as he's out to sea, the boat takes on water - he can't bail it out quickly enough to prevent the craft from sinking. In the freezing cold water, he abandons ship and manages to struggle ashore an inlet.
Abby, meanwhile, is finally allowing Robbie back into her own life, and for the first time in many years, they sleep together.
Kenny, now frozen to the core, manages to light a fire. In the morning a rescue helicopter spots him and he's taken to safety. He's surprised to be met by his father, Gordon, the kids, and finally, Abby. He finally sees her speak the words he's wanted to hear for so many years - that she loves him. But frustratingly, he can't hear the them. He awakens. He's back on the beach, freezing, and desperate to get a fire going…and again, he lapses into his dream world. He reconciles himself to all the important people in his life, but especially his one true love - that of Abby.
Daylight breaks, and the alarm has been raised that Kenny is missing. Gordon takes Abby on the ferry, and together they desperately try to find him. The coastguard have mounted a search and rescue, as the islanders wait helplessly. Only Charlie seems oddly calm about Kenny's disappearance. The tiny boat has been found and on the beach, Kenny's body is discovered next to an unlit fire. He's dead….
