MI6 asks for a favour: what could possibly go wrong? Stuart Gleeman, a private and introverted lawyer, is travelling to Colombia on business. Just before he leaves, MI6 asks him for a simple favour: deliver a parcel. However, once in Medellín, Stuart finds the intended recipients dead and himself framed for their murder. Trapped in a foreign city, he goes on the run, aided by a mysterious priest and the local lawyer he was meant to meet. Meanwhile, against the backdrop of the divisive 2014 Presidential election, which would see President Juan Manuel Santos win the 2016 Nobel Peace Prize, the drug cartel responsible for the murders is making a final play for power by threatening to assassinate a visiting British Prince. As the clock ticks down, Stuart realises that to clear his name and stop the attack, he must step up to the plate and take on the cartel.
