around Irwin, using code words and gestures. An infuriated Winter reaches out to Yates, an anti-social prisoner and a former officer and Apache helicopter pilot convicted of running a drug-smuggling ring. Bribed to inform about Irwin's plans for a reduced sentence, Yates informs Winter that Irwin intends to take over the prison, then raise the U.S. flag upside down to signal distress. Irwin organizes a plot to throw the prison into chaos. His intent is to show a friend, Brigadier General Wheeler, Winter's superior officer, that Winter is unfit and should be removed from command under the Uniform Code of Military Justice.

Winter then tells Irwin to return his flag, but Irwin replies, "It's not your flag", before he turns and
