Q: Passage: After a brief look at the Flyers' success in the 197374 regular season, head coach Fred "the Fog" Shero is introduced. It then looks at the Flyers-Rangers series that resulted in the first expansion team defeating an original six team in a playoff series. The film then examines the Flyers' Stanley Cup Finals series against the Boston Bruins. The documentary also covers the odd relationship between singer Kate Smith and the Flyers' team. 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. A brief mention is made of the LCB line (Reggie Leach-Clarke-Bill Barber).
