When a medical device fails on a former Chastain employee, an investigation is opened up, which pits Dr. AJ Austin against Quovadis. As Mina and Bell work to get to the bottom of what went wrong, Devon distracts himself with another patient who's experiencing mysterious stomach pains. Meanwhile, Nic forms a bond with her new partner at the clinic (guest star Miles Gaston Villanueva) and Conrad's relationship with the Barnett family (guest stars Evan Whitten and Daniella Alonso) continues to grow.

Conrad, Kit, Mina and the Raptor work to save the life of a med student in need of a triple-organ transplant, drawing Bell back to the OR for one of Chastain's riskiest surgeries yet. After the police find Julian's empty car in a nearby lake, Devon does some investigating of his own to find out what might have happened. Meanwhile, Mina and the Raptor hound Bell to halt his business with the risky medical device company, Quovadis, and Nic makes a rash decision regarding her sister.
