The Pitt, 6:00 P.M.

While attempting to distract himself from the anniversary of his mentor's death, Dr Robby introduces a fresh batch of interns to life in the ER.

Robby helps siblings navigate their elderly father's end of life care. Later, Samira fends off cops targeting a woman with a misunderstood condition.

After Whitaker struggles with a patient, Samira vows to keep him off the path that led to her own problems navigating emergency medicine. Nick Bradley's teen overdose case sets off a powder keg of emotions – as his parents cling to hope.

Bets are taken on the whereabouts of a stolen ambulance, while Santos learns a hard lesson, and Whitaker helps to tame 'The Kraken.'

Both Santos and Collins deal with their own moral – and legal – quandaries. Samira's careful approach earns praise from patients – and reproach from Robby. Javadi unintentionally upends McKay's attempts to help an unhoused patient.

While Robby handles an ultimatum from the hospital, Mel, Javadi, and Collins each handle unique mother-daughter dynamics.

After examining an influencer with strange symptoms, Samira pushes back against Robby. Santos contends with a patient accused of assault.

While Robby attends to an elderly patient with ties to Pittsburgh's history, other members of the team attempt to resuscitate a young drowning victim.

After an emotional debrief from Robby on a difficult case, Dana breaks up a waiting room brawl between two moms. Then, Whitaker finds common ground with 'The Kraken', and a car crash between a pedestrian and a former patient puts pressure on McKay.

With the Pitt down a staff member, Robby relies on his team to pick up the slack. Later, Santos finally voices her suspicions.

As Collins guides a surrogate through a difficult delivery, Robby does his best to keep a developing staffing situation under wraps. Meanwhile, McKay confronts her ex's overstepping girlfriend, and Whitaker watches Samira sniff out a drug-seeking patient.

As dozens of critical patients flood the ER, Robby and his team struggle to keep up amid quickly diminishing supplies. Later, Javadi's fast thinking impresses a key surgeon, and Mel keeps tabs on an injured mother and son.

As the night shift begins and the death toll rises, Robby refuses to give up on a mass casualty victim – even after Abbott intervenes. Unable to find an attending, Santos and Samira each attempt risky moves to save their patients' lives.

As the ER begins to quiet down, Robby struggles to cope with a loss, while Abbott and Samira are challenged by a patient's rapidly deteriorating condition.

As the day shift prepares to finally head home, Robby resorts to unorthodox methods to convince the father of a critically ill teen to allow treatment.
