Fifteen-year-old Sophie yearns to break free from her dysfunctional family. After one argument too many, she seizes an opportunity and takes the spare keys to her affluent friend Jade's house. While enjoying the spacious home she thought was empty for summer, she bumped into her friend's older brother Stephane. He, as fate would have it, was also planning on staying. Rather than insisting she leave, Step̌hane lets her into the house and his life. Loosely autobiographical, Spare Keys is a tender coming-of-age story about a summer that changes both Sophie and Stp̌hane.
