The hilarious Emmy Award-winning comedy series returns with further adventures of Martin, youngest member of the large, loud and chaotic Moone family living in rural Ireland, and his imaginary friend Sean Murphy. It's now the early 1990s and, on a trip to Dublin, Martin and best friend Padraic's latest scheme sees them becoming surprisingly successful door-to-door salesmen. The Moone house is bursting at the seams when Fidelma and Dessie move in with the baby, so Martin secretly sets to work creating his own luxury pad in the roof-space. And there's a blast from the past when Grandad's own imaginary friend reappears.
