An obesity treatment has been discovered, but before anyone can benefit, a dispute breaks out about who owns the discovery. David Marchmont, a patent lawyer, is asked to handle the case. There's one big problem, though: crucial evidence is missing--evidence that might have a bearing on the clinical trial two years before.

David's personal life has its own challenges. His daughter, Chloe, has a rare and serious genetic condition. His wife, Rachel, becomes friendly with a young researcher, Kate Flanagan, who is seeking a cure for Chloe's disorder; Kate, in turn, becomes concerned that her lab colleagues may be cutting corners on the obesity drug.

As evidence of mishandling mounts--then disappears--Kate, Rachel, and David find themselves caught up in acute ethical challenges and personal danger. Is biotechnology outstripping our capacity to make ethical decisions?
