It was a big year for women at the 2019 Sundance Film Festival. All four of the Grand Jury Prizes given to competition films were either directed or co-directed by women.

Filmmaker Chinonye Chukwu, though, broke new grounds. Her film “Clemency,” a moving death row drama, won the festival’s biggest prize, the Grand Jury Prize for her US Dramatic entry.

IndieWire shares that she wrote and directed “Clemency,” and has been directing short films since 2009.
