Yajima Manufacturing is a small factory in a part of Ota district in Tokyo. It is run by Yajima Koichi and his son Kentaro. One day, bobsleigh athlete Yanagida Miki suddenly visits with the request that they make a sleigh for her so that she can ride it at the Sochi Winter Olympics. Miki does not shrink away from the hardship of the minor event, and is cheerful and positive. Because a bobsleigh is a conveyance that Kentaro is unfamiliar with, he tries to turn down this request. But when he sees how seriously she is in training for the Olympics, he is moved by her passion and takes on this responsibility. Without sufficient funds, parts and blueprint, Kentaro fumbles to make the sleigh. Seeing him like this, the factory’s workers also pitch in to make the sleigh and before long, the unprecedented bobsleigh project gains steam.
