Based on the real-life saga of Kim and Krickitt Carpenter, as told in the same-titled book, the plot takes off after the couple is hit from behind by a fast-moving truck and Krickett is left in a coma. Upon waking she has no memory of her new husband, so the pair must rebuild their relationship from scratch.
