Hathaway remains on suspension from the hospital. While Hathaway is shopping at a family-owned neighborhood store, two teenagers, Duncan (EWAN McGREGOR - "Trainspotting," "Emma") and James (Currie Graham), rob it. The teens had planned a simple, nonviolent heist, but the situation escalates when the elderly store owner shoots and injures James. Duncan shoots the owner, and several customers are injured as well. Someone escapes and calls the police. Trapped inside the store, the robbers take hostages, including Hathaway and her 10-year-old neighbor, Robert (MASON GAMBLE - "Dennis the Menace").

After persuading the thieves to allow her to tend to the injured, Hathaway uses her medical skills and crude implements from the store to help the victims. Unfortunately, she is unable to save the elderly shopkeeper. She also negotiates with Duncan and James. Hathaway calms Duncan, who is upset that he killed the old man. Despite the tense situation, Hathaway sympathizes with him because she, too, killed an old man by accidentally giving him the wrong blood.

Later, Duncan attempts to escape, taking Hathaway with him. However, a police officer shoots him. The standoff ends. Duncan and James are transported to the emergency room, where Hathaway reluctantly relinquishes control of her patient, Duncan, to Ross. The hostages are fine and owe their lives to Hathaway. Later, Duncan dies, while James will probably live to be prosecuted.
