In the quiet suburbs of a mid-sized Canadian city, a resident named Elena experiences sudden, severe chest pain. She calls 911, expecting an ambulance to arrive within minutes, as promised in public service advertisements. However, when the paramedics finally arrive, they are already stretched thin, having just completed a long transport to a hospital that is at capacity. Elena must wait in the back of the ambulance for over an hour while the crew attempts to coordinate her transfer, a delay that causes her anxiety and physical discomfort.
