Poster image for Celtics City - S1 Episode 1

As the Boston Celtics celebrate their record 18th NBA title, the franchise's origins are traced back to the arrival of Red Auerbach in 1950 and his uncompromising vision for success. Auerbach builds a powerhouse led by Bob Cousy and Bill Russell, but racial tensions in Boston and beyond augur a tumultuous era ahead.
