An offhand remark from Danny inspires Frank to challenge himself. Already contemplating the state of his relationships with loving wife Joan (two-time Academy Award nominee Brenda Blethyn) and all-but-estranged son Rob (Jamie Sives), Frank is determined to shore up his own self-confidence. He will attempt the near impossible swimming the English Channel. As Frank plunges headlong into his new daily life, his astonished friends are swept along with him. Prodded by stalwart fish-and-chips shop owner Chan (Benedict Wong), the men support Frank, train him and keep their goal secret from his wife and son. Frank is unable to confide in those closest to him, but as the big day and moment of truth draw near, there is a sea change. Franks family confronts him, and he realizes that he must repair his strained family ties. As Frank and those closest to him discover or re-discover reserves of love and compassion, he realizes that he is also swimming from one part of his life to another.
