Homosexuality in the California mountains during the 1870s provides the basis for this drama, a very early gay film that centers on the reminiscences of a mountain man, Cyrus, who tells the tale of how he lost his lover, who was upset about the way other homosexuals kept changing partners. The young man went to see an Indian medicine man who told him that it was all right to have more than one lover. His mind at ease, Ephraim moved on to find others with whom to share his love.
Song of the Loon, based on a trilogy of novels by Richard Amory, was notable for its positive depiction of love and sex between men in romantic and positive terms, and particularly in its expression of the philosophy of free love. There is full-frontal male nudity and the film is erotic.
