She suffers from amyotrophic lateral sclerosis and is planning to pursue euthanasia with the help of her husband Paul and invites her family and her longtime best friend Liz to the house so they can spend her final days together. But there’s tension between her daughters, the uptight Jennifer and the wayward Anna, and it threatens to destroy her perfectly laid-out plan.
