Michael Mason (Richard Madden of Game of Thrones), an American pickpocket living in Paris, discovers that he is being chased by the CIA after stealing a bag that turns out to contain a bomb. CIA agent Sean Briar (Idris Elba from the TV series Luther) soon realizes that Michael is just a pawn in a much bigger game and decides to use him as an asset to reveal a large-scale conspiracy. Briar recruits Michael to help track the source. During a hectic 24-hour period, they must dare to trust each other in order to succeed in destroying the enemy. Sydsvenskans Malin Krutmeijer believes that Bastille day is "a rather entertaining and fast-paced story with car chases, fights and mass demonstrations. There is also a certain dynamic between the main roles, where Briar acts as a kind of hyper-competent older brother in a classic arrangement”.
