Battling a terminal illness, she dreams of being a superhero, and inspires other kids in the children's hospital to play out scenes from action films. One day, her mother Kathryn takes Jo back to her rural village to spend the rest of her short life with her family. Against all odds and battling the time left her, the whole village takes it upon themselves to make Jo's last wish a reality: to make a film and star in it.
