Franck Drevil (Guillaume Canet) is Team DCNS' star skipper, having won the latest Vendee Globe - the most prestigious round-the-world single-handed yacht race in the world. However, with this year's race approaching, a sudden accident forces Franck to withdraw. Franck's team member Yann Kermadec (Francois Cluzet), who has watched in Franck's shadow for ten years, sees his dreams suddenly come true as he replaces him at the last minute. Not only is Yann going to race his first Vendee Globe, but it will also be his first time racing on his own. Yann is fiercely driven to win, but the discovery of a young stowaway in the heat of the race will force him to put everything into question.
