Acclaimed filmmaker Barry Levinson recounts the dedicated efforts of a devoted marching band to support their hometown football team at all costs. It was during a chilly March night in 1984 that Baltimore Colts owner Robert Irsay made the rash decision to move his team to Indianapolis, and when the fans awoke the following morning that could barely believe the news. Realizing that they were facing the biggest challenge of their careers, the members of the team's volunteer marching band made it their mission to help build up a team that Baltimore football fans could truly be proud of.
