Carlota Moreau: A young woman, growing up in a distant and luxuriant estate, safe from the conflict and strife of the Yucatan peninsula, the only daughter of a genius - or a madman.
Montgomery Laughton: A melancholic overseer with a tragic past and a propensity for alcohol, an outcast who assists Dr Moreau with his scientific experiments, which are financed by the Lizaldes, owners of magnificent haciendas with plentiful coffers.
The hybrids: The fruits of the Doctor's labour, destined to blindly obey their creator while they remain in the shadows, are a motley group of part-human, part-animal monstrosities. All of them are living in a perfectly balanced and static world which is jolted by the abrupt arrival of Eduardo Lizalde, the charming and careless son of Doctor Moreau's patron - who will, unwittingly, begin a dangerous chain-reaction. For Moreau keeps secrets, Carlota has questions, and in the sweltering heat of the jungle passions may ignite.
