In the operating room Dr. Jenkins introduces Chelsea, an intern newly assigned as today's anesthetist, and staff immediately object to letting an inexperienced person handle a risky surgery. Colleagues demand oversight; Dr. Lester has approved and Kyle agreed, so Dr. Charles will supervise while Jenkins defends the choice.

Chelsea accepts the role and faces her first critical decision under scrutiny: the strict dosing limit leaves the operation's success hanging on her choice.
