A two-dwelling greystone cottage outside of London, World's End is home to Pauline, 1 55-year-old widow, her daughter Teresa, her son-in-law Maurice, and her grandson Luke. Pauline fears for her daughter, for she senses that Maurice is infatuated with another woman. As the summer draws on and the temperatures reach record levels, she finds herself forced to confront the lingering, simmering anger she still feels over the infidelity of her own late husband while watching her daughter's marriage come to an end.
