Guevara makes his symbolic "final journey" at night when, despite the danger and his asthma, he swims across the river that separates the two societies of the leper colony, to spend the night in a leper shack, instead of in the doctors' cabins. Later, as they bid each other farewell at an airport, Granado reveals that his birthday was not 2 April, but rather 8 August, and that the aforementioned goal was simply a motivator: Guevara replies that he knew all along. The film closes with an appearance by the real 82-year-old Alberto Granado, along with pictures from the actual journey and a brief mention of Che Guevara's eventual 1967 CIA-assisted execution in the Bolivian jungle.
