The keyword phrase functions as a noun phrase, with "ending" serving as the head noun modified by the proper noun "Patriots Day." The film's conclusion transitions from a dramatized narrative to documentary footage, culminating in the capture of the second perpetrator and featuring testimonies from the real-life individuals involved.
The narrative climax depicts the discovery of Dzhokhar Tsarnaev hiding in a boat in a Watertown backyard, following a city-wide lockdown. Law enforcement utilizes thermal imaging from a helicopter to confirm his presence, followed by a tactical operation involving flash-bang grenades that results in his surrender and capture. The film portrays this manhunt's resolution through the perspective of fictional composite characters, such as Mark Wahlberg's Sergeant Tommy Saunders, who represent the collaborative efforts of multiple police departments and federal agencies.
This docudrama-style conclusion serves to honor the actual people affected by the tragedy. Following the capture, the film presents a montage of interviews and personal footage of the real survivors, first responders, and officials, including Patrick Downes, Jessica Kensky, and the late Commissioner Ed Davis. This final sequence acts as a tribute, emphasizing themes of community resilience and the "Boston Strong" spirit, providing an emotional resolution centered on the victims' and the city's recovery rather than solely on the criminals' fate.
