Ivan's routine existence is upended with the arrival of Ruby, a young elephant taken from the wild, prompting him to see his environment through new eyes. Inspired by Ruby's plight and Stella's passing wish, Ivan taps into his long-dormant creativity and empathy to hatch a plan to give Ruby a better life, leading to a poignant journey of friendship, art, and the quest for a place to call home.
