Anja works at a bank and in her spare time she is active in the volunteer fire department. When fire brigade leader Rainer makes the divorced mother of two a temporary squad leader, not everyone agrees. Especially not Meike, who is new to the squad.

A year after firefighters Anja and Meike met, one would think that they had become friends - if only they weren't such grumps. Anja has lost her house and now has to move in with Meike, but the latter would actually prefer to return to the army.
