Wilder

Rosa Wilder is called in to investigate when Betschart, a policeman from the village of Oberwies, is murdered, while trying to settle an argument in the village pub.

Rosa Wilder identifies two suspects in the police officer murder case; Elias and Zingg are involved in a mysterious death; the Räber family are the victims of blackmail.

Dani Räber does not give in to Strunz's blackmail, as the documents are worthless; Zingg, suspected of murder, is freed, but Kägi stays on his trail.

The party organised by the Räbers to celebrate the end of the dam project is overshadowed by a tragic accident; Kägi asks Rosa to help him with his investigation; Strunz, who needs money in a hurry, prepares for a kidnapping.

Rosa's son and father have been kidnapped by Strunz, and to free them, she'll need to take risks; Liechti, the accountant, risks going to prison if Strunz is arrested and confesses.

Elias, the key suspect in the policeman's murder, vanishes without a trace. A manhunt ensues which proves extremely taxing for everyone involved; Rosa realises that in Oberwies, nothing is as it seems.
