Alex Taylor, a team leader at the Canadian Intelligence and Security Establishment, is tasked to spy on an unemployed shoe salesman who is potentially a Chechen operative. Lesage anonymously gives the Chechen a model train starter kit to enliven his dull life. When Alex sees the surveilance video she believes that the friends who are visiting are using the model train as a cover for a bigger terrorist conspiracy until she gets the translation of video which confirms they are 'nerds playing with trains'. A moment later Burt mistakes modelling clay for C-4 explosives. The A team, led by Alex's ex-boyfriend Peter, are tasked to take down the Chechen and his friends. After Lesage informs Alex that it is not explosives and says that the Nathan, the new kid on the team, gave the Chechen the train set Alex confesses to everyone that there are no explosives and it was all a mistake.
