Diarios de Motocicleta

As the film starts we are introduced to what appears to be your average young man. He is playing sports, attending college to become a doctor and has a close family. Ernesto and his friend decide to travel over the next several months until they reach their final destination to volunteer at a Leper Colony, as this is what Ernesto believes he will specialize in as a doctor.
We see during the course of his travels, his personality grow into what would eventually make him a leader of the revolution of Latin America. As the two travel they meet many different people and it is through these interactions that Ernesto realizes his calling.
He struggles with the decision to leave his girlfriend to pursue his passion to help others at the Leper Colony, but promises to return to her.
He meets a man and asks him for help. The man learns through conversation these two are doctors, so he asks them to look at his neck. Immediately, without hesitation Ernesto tells him it is a tumor, his friend tells the man it is a cyst. The man becomes upset at his diagnosis, and sends them away offering little help to them. His friend scolds him basically telling him he should not have been so direct with his diagnosis. Ernesto believes he told the man what the man needed to know.
His next encounter was with a couple forced to travel to find work, leaving their son behind for his safety. He watches as the husband is chosen to work for the mining location, but argues with the person in charge of choosing because he doesn't offer the men food or drink. He is angered by their lack of compassion for the men that will be working for them.
He watches the poor walking to find a better place to live. He speaks to some and hears the stories of farmers being forced from their property. He attempts to help a sick older woman and when he realizes there is little he can do he realizes he can give her pills and tell her they will make her better. Giving the woman hope and peace of mind, instead of telling her she is dying.
When he finally arrives at the Leper Colony, he refuses to wear gloves. He doesn't want the people with this disease to feel more isolated than they already do. He shakes their hands and cares for them with respect and compassion.
As the film progressed Ernesto turned into a man of courage and compassion for others. Unfortunately his passion to help others is what led to his violent manner as a revolutionist and his untimely demise.
