SUN CHILDREN is the story of 12-year-old ALI and his three friends. Together they work hard to survive and support their families, doing small jobs in a garage and committing petty crimes to make fast money. In a turn of events that seems miraculous, Ali is entrusted to find a hidden treasure underground. He recruits his gang, but first, to gain access to the tunnel, the children must enroll at the Sun School, a charitable institution that tries to educate street kids and child laborers, close to where the treasure is located.
