Sean (O'Dowd) is the imaginary friend of 10-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.“已经过去六十年了，当初那个时代已经彻底的被葬下了，你即便是苏醒了之后又能做什么？”杨间目光微微垂下，他想到了观江小区，想到了以前的那些朋友。
