It chronicles the National Hockey League's (NHL) Philadelphia Flyers from their beginnings as an expansion team in 1967, to their back-to-back Stanley Cup championships (1974, 1975), and three straight Finals appearances (1974–76).

The film includes clips and photos from the era, along with interviews with players, writers, broadcasters, and other individuals involved with the Flyers and/or NHL hockey during that period.

The documentary shows how the early Flyers were physically beaten by the St. Louis Blues, and their consequent decisions to bring in bigger and tougher players, so as not to be pushed around in the post season.

This resulted in an aggressive team that bent rules, and used fighting and intimidation as a tactic – nicknamed the "Broad Street Bullies".

Broad Street Bullies profiles Dave "The Hammer" Schultz, his impact on the team, and influence on the development of a new attitude towards ice hockey in Philadelphia.

It then focuses on the final game of the series, which culminated in the Flyers' first Stanley Cup championship, as well as the response by fans.

The documentary explores the dichotomy between the love of the team in Philadelphia and the hate it generated in other cities, epitomized by Flyer great Bobby Clarke.

The post-season title defense of the Stanley Cup begins with a section on the Islanders coming back from a 3–0 deficit to tie the series, and the Flyers' favorite bar, Rexy's, burning down.

The documentary then returns to Schultz and a song he recorded, and examines his fighting tendency and the impact it had on other teams around the league.
