Nicole runs into trouble with her evidence. On a family vacation in Austria, Björn tries to relax — but one serious slip shows he still has work to do.

Björn stages a day care break-in to deal with yet another problem. A chilling message and a surprise visit from the parents' group complicate things.

The parents' group pushes to inspect the basement. Disturbed in his sleep, Björn's inner child nudges him to deal with the teens across the street.

Björn agrees to meet with Laura's brother Kurt. As the blackmail escalates, his creative plan for the Holgerson hostages takes a dark turn.

When Björn learns about Kurt's past, he grows suspicious. With Kurt, Nicole, pushy parents and a tricky delivery, he's got a lot on his mind.

Nicole shows interest in Kurt and questions the "coincidences" in the Holgerson story. Meanwhile, Björn comes up with yet another explosive plan.

Björn enjoys a false sense of security, but the Holgersons come knocking and he makes a risky promise. Sascha plots to keep the parents in check.

Björn makes Kurt an offer he can't refuse... or can he? As things get ugly in the basement, staying calm is Björn's last defense against chaos.
