Bochum: In the 2nd episode of the new season, the firefighters are called to a chimney fire in the evening. The fire threatens to spread and must be brought under control quickly. However, the fire in the chimney must not be extinguished with water.

 In addition to the ambulances, the fire department also has emergency vehicles, in each of which a paramedic from the fire department accompanies an emergency physician from the hospital to serious emergencies. An elderly woman complains of shortness of breath and chest pains; everything points to a heart attack. Every minute counts. 

Survival is also at stake when a bee colony is relocated from the garden of a residential building.
