This season, creator and host Sarah Ellison takes an in-depth look at the Harbaugh family and its fascinating and often controversial ultra-competitive “fighter” approach to life. With over 25 interviews with family members, friends, co-workers and reporters conducted over the course of a year and woven into a story told over nine episodes, fans get a glimpse at what makes this family tick.
