A Few Good Men (1992)

In this military courtroom drama based on the play by Aaron Sorkin, Navy lawyer Lt. Daniel Kaffee is assigned to defend two Marines who are accused of the murder of a fellow leatherneck at the base at Guantanamo Bay. Kaffee generally plea bargains for his clients rather than bring them to trial, but Kaffee and his assistant Lt. Commander JoAnne Galloway are convinced that there's more to the matter than they've been led to believe. The two Marines reveal that the victim died in the midst of a hazing ritual known as "Code Red" after he threatened to inform higher authorities that they opened fire on a Cuban watchtower.
