Don moves into a house left to him by his recently deceased grandmother and meets his Nan's over-enthusiastic carer Eddie. Don decides to get a lodger. He ends up choosing Abby, the girl he was in love with as a teenager and still fancies. The trouble is, Abby isn't single - she has a snobby boyfriend called Karl.
Sam has a new boyfriend who is everything Don isn't - mature, reliable, clever and not at all self-obsessed. Once more Don has to deal with a fraught love life that involves dates with an aristocrat, a tramp and a really angry woman. On top of that he is sucked into taking part in Top Gun - The Musical, tries therapy and even sells his soul to become a corporate highflyer.
