The film tells the inspiring true story of Dream Alliance, an unlikely racehorse bred by small town Welsh bartender, Jan Vokes (Toni Collette) perhaps as a way to add meaning to what she feels is a pretty humdrum life. With very little money and no experience, Jan convinces her neighbours (including Damien Lewis), a group of down-on-their-luck Welsh villagers, to chip in their meagre earnings to help raise Dream in the hopes he can compete with the racing elites. The group's investment pays off as Dream rises through the ranks with grit and determination and goes on to race in the Welsh Grand National showing the heart of a true champion.
