S5·E1 Large-scale deployment and the way to the fire is blocked

Bochum in the early evening: Dense, black clouds of smoke rise from a company building. The fire department is quickly on the scene - but the premises are locked. As the fire threatens to spread and every minute counts, the emergency services have to gain access as quickly as possible. In addition, the dispatch center receives a domestic emergency call. An elderly lady has pressed her emergency button and is not responding to any call. The fire department sends the rescue service. At the scene, neighbors report that the lady is seriously ill. For the rescue workers, a race against time begins, because her apartment door is specially secured.
