Somerset, October 2014. When Clover Catto (Ellie Kendrick) receives a call telling her that her younger brother Harry (Joe Blakemore) is dead, she must return to her family farm and face the man she hasn't spoken to in years: her father Aubrey (David Troughton). She is shocked to discover her home changed forever by the devastating floods that destroyed the area six months earlier, and Aubrey a tormented shadow of his former self. As she learns what has been going on in her long absence she and her father forge a new understanding, but can it withstand the troubles that they face on the ravaged farm as well as the truth of what drove Harry to take his own life?
