An earnest account of how one 13-year-old boy rescued his African village from drought by harnessing windpower to operate an irrigation system. A rather dry subject (pun not intended) which is filled out with a large amount of backstory regarding the boy's home life and sometimes difficult relationship with his father. Both Chiwetel Ejiofor and Maxwell Simba give strong performances as father and son. Ejiofor also writes and directs.
