Neddy Emory and her brother Charles head up Angiras, a family-owned start-up with a radical innovation that will transform patient care for cystic fibrosis. They're about to go live with a revolutionary life-saving medical device. But they've hit a major snag. Critical research is unraveling and, to their shock and horror, one-by-one, team members are falling mysteriously ill.
Neddy and Charles race to move the project forward, while struggling to keep their employees safe. Failure is not an option. Without the device, their younger brother Daniel will die. But Neddy begins to suspect the company's innovative research methods are being tampered with. When probed, Charles gaslights her. He refuses to slow down, claiming he is Daniel's only hope.
Torn between loyalty to her family and the welfare of the staff, Neddy desperately searches for the truth. Then the unspeakable happens. A fatality. Charles appears to finally be persuaded. But his next move shocks her, and she realizes: the danger is only beginning. And she is on her own.
