Evie Landry is slipping, and she knows it. She has trouble remembering the names of her children, and even of her loving husband, Nick. Nothing in the house seems to be in the right place. Sometimes, at night, she wakes up terrified of Nick and runs away, but the neighbors always call him and he takes her back to the place she no longer believes is her home.
When their doctor tells Evie and Nick that she probably has Alzheimer's disease, Nick does everything he can to protect her, but one day she attacks him on the driveway and puts him in the hospital. The pressure to send her to long-term care becomes overwhelming. Early one morning, before the decision can be taken out of Nick's hands, he bundles Evie into their car and they begin a thousand-mile journey from Central California to Canada and their only hope of staying together.
