PATRIOTS DAY

PLOT

On April 15, 2013, brothers Dzhokhar and Tamerlan Tsarnaev detonate two bombs during the Boston Marathon, causing widespread panic. A young couple, Patrick Downes and Jessica Kesky, are injured and taken to separated hospitals, where they're both required to have their legs amputated; while family man Steve Woolfenden is injured and
separated from his young son, Leo, who is rescued by the police and taken to a safe location.

FBI Special Agent Richard DesLauriers is assigned to investigate the bombings in collaboration with Boston Police Commissioner Ed Davis and Watertown Police Sergeant Jeffrey Pugliese, while Police Sergeant Tommy Saunders searches for evidence and helps people that have been injured or separated from their loved ones in the chaos, including Patrick and Jessica as well as Steven and Leo. FBI analysts review footage of the bombing and identity Dzhokhar and Tamerlan as suspects, but DesLauriers is reluctant to release their pictures to the public without further evidence, although Davis persuades him, while Pugliese's men conduct door-to-door searches for the pair.

Attempting to lay low, Dzhokhar and Tamerlan kill officer Sean Collier to steal his gun and carjack student Dun Meng, announcing their plans to conduct another bombing in New York City. Meng manages to escape when the brothers stop at a gas station and call the police. Saunders arrives at the scene, learns of the brothers' plan and is given the stolen car's GPS tracker, leading police to the pair's hideout. Tamerlan is injured in the ensuing shootout, and taken to the hospital, where he is later pronounced dead, while Dzhokhar escapes. Tamerlan's wife Katherine Russell and Dzhokhar's college friends are later detained and questioned, but Katherine refuses to disclose any knowledge of her husband's illegal activities, while Dzhokhar's friends appear oblivious to his plans, despite having earlier found bomb components in his possessions. A local man later finds Dzhokhar hiding under the sheets of his boat and calls the police. Dzhokhar is quickly surrounded and arrested after a brief standoff, as Saunders and his colleages celebrate.

The epilogue reveals that Dzhokhar has been sentenced to death by lethal injection and is awaiting for an appeal in federal prison that his college friends were arrested for obstructing the investigation and that Russell is still under investigation for her possible involvement, followed by statements from the authorities responsible for the investigation and the survivors of the bombing, celebrating Boston's newfound sense of unity, and a dedication to the victims, survivors, first responders, medics, and law enforcement agents that were involved during the events
