At Grey Sloan Memorial Hospital, married power-couple Dr. Cameron Adams (Chief of Surgery) and Dr. Lucas Adams (Chief of General Surgery) stand on the precipice of fatherhood as their surrogate, Dr. Jo Wilson, reaches her exact due date. Their son, Leo Christopher-Frances Adams, is the result of a groundbreaking trial making both Cameron and Lucas his biological fathers. However, the hospital is weighed down by escalating tension: general surgery resident Mika Yasuda has developed an intense, volatile obsession with Lucas, ignoring repeated warnings from the entire attending staff—including Meredith, Jackson, Alex, Amelia, Maggie, Arizona, Jo, and Carina—to back away. The fragile professional boundaries shatter completely when Jo's labor strikes right in the middle of a crowded hallway, instantly plunging the hospital into chaos and setting the stage for a dangerous collision between personal obsession and high-stakes medical life.
