A scientist working in embryology, driven by ambition and arrogance, illegally creates a part-pig part-human embryo. Defying advice from her only confidante, she recklessly decides to take the experiment one step further, and surrogate her creation - not expecting the pregnancy to be viable.. but it is. Shocked and afraid, she isolates herself, in turmoil about what she should do, as the pregnancy relentlessly progresses and she must face her ultimate responsibility alone.
