"The Friends of Eddie Coyle" (1973) Robert Mitchum, Peter Boyle & Richard Jordan

Eddie Coyle is a low-level gunrunner based in Quincy, Massachusetts. He supplies pistols to a bank robbery crew led by Jimmy Scalise and Artie Van, first obtaining the guns from a fellow gunrunner named Jackie Brown. At the same time, Coyle is facing several years of jailtime for a truck hijacking in New Hampshire set up by Dillon, who owns a local bar that Coyle frequents. Coyle cooperates with ATF agent Dave Foley in order to get his sentencing cleared, but is unaware that Dillon is an informant for Foley; Dillon meets with Foley in person every week to receive $20 from him.

After kidnapping Mr. Partridge, a bank manager, the crew successfully rob the South Shore National Bank and make a clean getaway. Afterward, Coyle meets with Foley to discuss his sentencing. Coyle tells him that he knows a gunrunner, Jackie, whom he could potentially have Foley arrest in order to ease the sentencing; Foley sits on this idea. Meanwhile, Jackie meets a hippie couple in Cambridge who wish to purchase M16 rifles from him. He reluctantly agrees to sell them in a discreet location at a specific time. Jackie then meets with Coyle who requires Jackie to acquire guns for the next day. While unsure at first if he can complete the task, Jackie complies and heads to Rhode Island later that night with an associate to get the guns, which he is successful in doing.

The crew robs a second bank, this time in South Weymouth. Towards the end of the robbery, one of the tellers triggers a silent alarm and is shot dead by one of the robbers, requiring a hasty exit. The crew are able to flee without any police following them, but become wanted for murder as a result. Afterward, Jackie meets Coyle in the parking lot of a Dedham grocery store to deliver him the guns. Once the exchange is finished, Coyle calls Foley from a payphone to tip him off about Jackie's exchange with the hippie couple at the Sharon train station. There, Foley and a group of agents watch the area from afar with sniper rifles. The couple arrive, though Jackie tells them to meet him elsewhere at a later time, believing that he is being watched. Once the couple leaves, Foley and his team move in to make the arrest. Jackie recognizes the agents' cars and attempts to flee, but is boxed in at the exit and arrested, immediately realizing that Coyle had set him up.

Foley tells Coyle at their next meeting that Jackie's arrest was not enough to clear Coyle's sentence. In preparation for the third robbery, the crew moves in to kidnap the bank's manager, but are ambushed by Foley and other ATF agents and placed under arrest. The next day, Coyle decides to tip Foley off about Scalise and his crew, but is unaware of their arrest. Foley shows him the arrest in the newspaper and departs, leaving Coyle anguished. Soon after, Dillon is told that a mob boss wants him to assassinate Coyle, thinking that Coyle ratted out the robbery crew. Dillon invites Coyle out to a Boston Bruins game at the Boston Garden along with a hood whom Dillon claims is his "wife's nephew". At the game, Coyle becomes severely drunk and eventually passes out during the car ride afterward. The hood drives them to a discreet location, where Dillon shoots Coyle in the head. They swap out cars in the parking lot of a bowling alley and leave.

Dillon and Foley meet outside Boston City Hall the next day, where Foley thanks Dillon for giving him Scalise and his crew. Foley is largely unconcerned that Dillon cannot tell him who murdered Coyle, leaving the impression that he knows Dillon is involved, but likely would not have pursued the killing of Coyle. After they finish conversing, they walk away in separate directions.
