It turns out that imaginary friends run in the family when Grandad's childhood pal George Gershwin, a cool, piano-playing guy, turns up to fulfil his bucket list - so Martin, Sean and Crunchie Haystacks embark on a series of adventures to help him. Also, with summer just around the corner, Martin takes an unusual approach to his exam revision.
Sean is the imaginary friend of 12-year-old Martin Moone, the youngest child of a family living in a small town in Ireland. Martin has a unique perspective on life aided by an imaginary friend.
His imagination comes into play both in his childish drawings, which come alive through animation, and in the ridiculous schemes he comes up with, against Sean's better judgement. With Sean's help, Martin negotiates life as the youngest in a chaotic, scatter-brained family.
