Serge Ibaka escaped the war-torn streets of the Congo and played his way to the top of the NBA. In Son of the Congo, he returns to his native country, revisiting the empty lots where he slept and confronting the stark reality facing Congolese youth.

Son of the Congo will premiere at SXSW on March 14. Following its SXSW premiere, it will debut on Grantland, in five parts, on March 23-27. The film will air on April 17 at 8 p.m. ET on ESPN.
