Comeback Mack, recounts how Andy Mahr’s daughter MacKenzie, a high school volleyball player who also plays on a national team, sustained two extremely painful and season-ending injuries separated by only a few months. The video, one of Andy’s personal projects shot during Covid-19’s shut down, captures her strenuous rehab and her determination to return to the sport she loves. ​“It was good for her and great for us,” he says of the emotional bond they experienced during filming. ​“She’s young and fearless for her age.”
