The Master Plan details Bane's daring endeavor of capturing Doctor Pavel and crashing the Wreckage Brother in a very elaborate and complicated manner.
The Master Plan is in direct opposition to the Flight Plan. The eternal struggle between the two rival stratagems is examined by Bravo Nolan in the Plane Scene.
The post-credit scenes make several references to a plan. For example, Bane claims "our plan is proceeding as expected" while confronting businessman John Daggett. Whether this is a reference to the Master Plan, a new plan or even the Flight Plan is unknown; however, it grants an insight into Bane's obsession with planning.
