Plot

When a bomb destroys a health clinic, Cole comes in off-duty to help and encounters a pregnant victim.

Frank Kroll started a program of training firemen as commercially interesting bonding. It may pay off immediately as a bomb-caused major cave-in makes numerous victims requiring combined efforts. Gambler Wyatt tries his hand at chess and braves another bomb, followed by the while team, and does more unauthorized emergency surgery.—KGF Vissers

Wyatt Cole (Tom Everett Scott) tries his hand at chess. The ambulance service is preparing a programme to work in coalition with the fire brigade. Crazy Joan (Victoria Bidewell) arrives after hiting her head agains a food spender several times. Two Japanese ambulance drivers, Didi (Natalie Sky) and Gogo (Kevan Ohtsji), the representatives from a fellow city, think that USA's ambulance drivers are rude and unprofessional. All this was Frank Kroll (Curtis Caravaggio)'s idea, but Ángela de la Cruz (Tracy Vilar) thinks it's only a waste of time.

The janitor of a hospital, Sloman (Fulvio Cecere) puts a bomb in his workplace. Although a security lady notices Sloman's weird behaviour, it's too late to evacuate and the bomb goes off. There are many injured people and many casualties.

Everybody is looking for Jill Neuwirth (Michelle Harrison), one of the managers of the clinic, who is heavily pregnant. Jill is trapped among the debris, but she looks alive and well. John "Sack" Hallon (Omari Hardwick) and Wyatt help her. Another bomb has been found. The fire-fighter who was with them both runs away, aledgedly because he had children to take care of. Alice Alden, M.D. (Elizabeth Reaser) watches on TV how some of the paramedics refused to leave, and she knows that Wyatt and Sack are inside the building. They go out to save a child.

Jill's husband, Charlie (Kett Turton) enters with Sack and Wyatt to rescue her. She has started to feel cold, and has trouble breathing. Jill wants Wyatt to save the child if he has to choose between the baby and herself.

Leslie Brown (Linnea Sharples) speaks with sign language, and she recognises Sloman as the person who put the bombs. Ángela enters on her own volition as well. Alice refuses to let police officer White to speak to Sloman before he gets stabilized. Sloman wanted to die, so now he refuses treatment.

Jill is freed, but she's in shock. Jill dies. Wyatt is going to give a Cesarean to Jill. The baby is born. Alice takes care of him.

Gogo survives because of the on-spot treatment Ángela has given him.
