After finishing a tense emergency heart repair in the OR, Dr. Reed answers personal calls and reassures her husband about a canceled flight. The tone flips when hospital staff interrupt: a man collapses in the ER after being given something at a nearby encounter. Paramedics bring him in gasping; Dr. Reed is summoned. The team stabilizes him but then identifies anaphylactic shock triggered by sildenafil. The episode ends with the immediate medical crisis contained, but the cause and consequences, why he ingested the drug and whether he recovers, left unresolved as Dr. Reed prepares to treat her husband.
