Based on the best-selling book of the same name by Pete Brown, the film focuses on the adventures of the robot Rose (voiced by Lupita Nyong'o). Drifted to an isolated island by an accident, she deviates from the programme's preset trajectory and has to face treacherous living conditions and try to establish relationships with wary and hostile wild animals. As Rose meets a little grey goose (voiced by Kit Connor) and becomes his "mom", she gradually finds a sense of belonging on this deserted island. Defined programming is about to be broken, and a spiritual story of love is about to unfold.
