In this second and final episode, Guy Martin's adventures in Colombia continues as he meets face-to-face a former employee of Pablo Escobar. Soon afterwards, Guy visits some like-minded local racers and tries his hand at 'gravity racing' on specially made bicycles on a nearby mountain road. Later on after a trek through the forests, we find the most unlikely of machines, a drug cartel's smuggling narco-submarine and Guy gets to go inside it. After returning back, a local special brew is in order and has some interesting effects. A street patrol with the Police to experience the impoverished side of Colombia and then a chance to try the new transport system in Medellin. Finally a chance to go circuit racing with a big difference, truck racing in a fuel tanker !.
