Prueba de fuego

A woman moves into a house she has just inherited. In it, she finds several belongings of her grandfather, a known smuggler, which she dares not touch. Coincidentally, she befriends Line Wisting, an old schoolmate, and together they open the safe in the basement, where they discover money, some documents and a pistol that they hand over to the police. In parallel, the case of the missing taxi driver that William Wisting has on the table, and that has been stagnant for too long, seems to finally start. There are new clues that lead him to other crimes... one of them committed with the gun that his daughter Line found. The case had closed with the arrest of a man who had always sworn to be innocent. Contrary to the opinion of his colleagues, Wisting believes that no one has yet found the correct key to solving the two cases.
