Patriots Day review: True tale of riveting manhunt
On the morning of April 15, Dzhokhar Tsarnaev (Alex Wolff) and his brother Tamerlan (Themo Melikidze) head into Boston with bombs concealed in rucksacks.
They move into the thick crowds of spectators thronging the city's marathon course, drop the bags and move to safety before detonating the devices near the finish line.
The blasts injure hundreds and Sergeant Tommy Saunders (Mark Wahlberg) and wife Carol (Michelle Monaghan), a registered nurse, are on the front line during the subsequent manhunt.
Their resolve us tested along with Boston mayor 's Thomas Menino (Vincent Curatola) and other figures in public office including Police Sergeant Jeffrey Pugliese (JK Simmons).
Meanwhile, Dzhokhar and Tamerlan steal a car belonging to student Dun Meng (Jimmy O Yang), which they intend to drive to New York to carry out more atrocities.
Director Peter Berg's bombastic approach to action sequences sets our pulses racing and he effortlessly holds us in a vice-like grip for more than two hours, even if we know the chain of events from news coverage. Wahlberg portrays another steadfast all-American hero, who refuses to let anyone harm the city he loves.
