After dealing with various bureaucratic processes and enduring many unnecessary police searches, Ernesto and Alberto cross into Venezuela, which is more prosperous than Columbia. They hitch a ride in a van going towards Caracas, which takes a long time due to dangerous mountain terrain and several police checkpoints. Ernesto has another asthma attack during the journey, from which he only recovers after Alberto gives him an injection of adrenaline.
