Idyllic 1960s. Best friends Alice and Selina are surrounded by a peaceful and harmonious suburban neighbourhood - tranquil surroundings, beautifully manicured houses, meticulously mown grass... They both have successful spouses and beloved sons of the same age. But a sudden tragic accident shatters their happy lives to pieces. Guilt and paranoia will overwhelm them, breaking their sisterly bond, and the psychological games that ensue will expose their true colours and show how cruel a mother's instincts can be. This suspenseful film brings together a solid Hollywood acting duo - Oscar winners Anne Hathaway and Jessica Chastain.
