The Departed

In 1980s Boston, a complex game of deception unfolds as Irish mob boss Frank Costello introduces himself to a young Colin Sullivan, who is groomed as his spy inside the Massachusetts State Police and later becomes a career criminal rising through the police ranks. Meanwhile, another undercover cop, Billy Costigan, infiltrates Costello's organization, unaware that Sullivan has been planted within the police force. As both sides struggle to uncover the mole among them, the lines between loyalty, deception, and survival become increasingly blurred, culminating in a tense showdown that will leave only one man standing.
