Dalíland tells the story of the later years of the strange and fascinating marriage between the genius Salvador Dalí and his tyrannical wife, Gala, as their seemingly unshakable bond begins to stress and fracture. Set in New York and Spain in 1973, the story is told through the eyes of James, a young assistant keen to make his name in the art world, who helps the eccentric and mercurial Dalí prepare for a big gallery show.
