Somerset, England. Trainee veterinarian Clover Catto (Ellie Kendrick) returns to the farm where she grew up after hearing news that her brother Harry (Joe Blakemore) has died in what appears to be a suicide. Finding the family home in a state of horrendous disrepair following the 2014 floods that devastated the area, Clover is forced to confront her father Aubrey about the farm, the livestock and, crucially, the details surrounding Harry's death.
