1971, the American photographer Loren McIntyre finds himself stranded in the depths of the Amazon rainforest, on the border between Brazil and Peru. Finding refuge with the Mayoruma tribe - the famous and elusive 'cat people' of the Javari Valley, McIntyre must adjust to a strange new way of life. Before long he finds his perception of the world beginning to change, and an unusual relationship starts to develop with the Mayoruma chief - is McIntryre really able to communicate telepathically with the headman? Petru Popescu's narrative account is interspersed with notes from McIntyre's diary to create a fascinating and disorientating account of an extraordinary true story.
