Elsa and Clive, two young rebellious scientists, defy legal and ethical boundaries and forge ahead with a dangerous experiment: splicing together human and animal DNA to create a new organism. Named "Dren", the creature rapidly develops from a deformed female infant into a beautiful but dangerous winged human-chimera, who forges a bond with both of her creators - only to have that bond turn deadly.
Genetic engineers Clive Nicoli and Elsa Kast hope to achieve fame by successfully splicing together the DNA of different animals to create new hybrid animals for medical use.
