Staffers at Chastain are going to be very busy in The Resident Season 5 premiere, and one of the doctors has a connection to patients brought in during the crisis.

As revealed in the logline for “Da Da,” the ER is sent into a tailspin following an attack by cybercriminals, and it’s up to the hospital’s CEO, Dr. Kit Voss (Jane Leeves), to figure out whether or not to pay the ransom. Everyone is left vulnerable when it turns out Dr. AJ Austin (Malcolm-Jamal Warner) deals with a personal connection to patients brought in during the attack. You can get a peek at that in the photos below.
