Samantha (Naomi Watts) and her husband Cameron (Andrew Lincoln) have a happy family. They yearn for a free life and travel with their children every year. This year, the couple decided to go to Thailand for vacation. Unexpectedly, in an accident, Samantha injured her spine, resulting in complete paralysis below her chest. Samantha will bid farewell to her beloved outdoor sports forever, and can only spend the rest of her life in a wheelchair. The huge blow made Samantha change her cheerfulness and optimism in the past, and fell into depression. She even thought about death. One day, the children brought back an injured little magpie from outside and gave it to Samantha to take care of. The fragile little life in front of her aroused Samantha's desire to protect and reawakened her desire to survive.
