This Film is about the life cycle of the Southeast Pacific humpback whales, between their feeding grounds in the Antarctic and Sub-Antarctic , and their mating grounds in the Tropic. It was shot on super 16 mm in the pacific coasts of Colombia and the Patagonian fjords in Chile. A song that talks about the whales, mixed with their songs, was specially composed for the documentary by two of the preeminent masters of the traditional Colombian Pacific music: Hugo Candelario and Camilo Vargas. In spite of being a protected species, humpbacks continue to face many dangers that threaten their existence.
