A contemporary interpretation of John le Carré's best-selling spy novel, which follows hotel manager Jonathan Pine (Hiddleston) in his quest to bring down international arms dealer Richard Roper (Laurie). Pine, a former soldier, is thrust into a world of international intrigue when he is recruited by a British intelligence officer (Colman) to infiltrate Roper's inner circle. To get to the heart of Roper's vast empire, Pine must withstand the allure of his beautiful girlfriend Jed (Debicki) and the suspicious interrogations of his venal chief of staff Major Corkoran (Hollander). In his quest to do the right thing, Pine must first become a criminal himself.
