In a remote, top-secret lab, a group of scientists led by Dr. Simon Ziegler has created a synthetic being named Morgan, who, despite being just five years old, has the physical appearance of a teenage girl. Morgan embodies the pinnacle of artificial biological engineering, a next-generation leap in evolution with the potential to revolutionize the world. However, an unexpected and violent incident involving Morgan prompts corporate troubleshooter Lee Weathers to visit the facility to conduct a risk assessment. Lee is a no-nonsense and calculating consultant whose sole focus is to evaluate whether the project should continue or be terminated.

Inside the facility, Lee observes the complex emotional attachments between Morgan and her caretakers, including behaviorist Dr. Amy Menser, who treats Morgan like a human child, and Dr. Kathy Grieff, who has formed a maternal bond with the creation. The team's dynamics are complicated by their diverse reactions to the incident, with some arguing for empathy and understanding, while others stress caution due to Morgan's unpredictable nature. As Lee delves deeper, she encounters a web of desires, fears, and moral compromises among the staff, which raises serious questions about the capacity for artificial entities to possess human-like traits and the ethical boundaries of such scientific experimentation.
