Breitwieser spends a troubled night in a Swiss basement holding cell in the police station from where he was detained before.
The next morning, a police inspector named Roland Meier pays him a visit.
Meier assumes Breitwieser to be a petty thief seeking to profit off lightly protected museums.
He questions Breitwieser about the disappearance of a bugle from the Wagner Museum.
Despite denial from Breitwieser, Meier, who prefers patience and persistence, reveals the events of the theft day.
An employee at the museum noticed the missing bugle after seeing a man engaging in suspicious behavior.
Breitwieser shows signs of distress after hearing that the evidence against him was already collected before he could tamper it.
Meier attempts to coax a confession out of Breitwieser by bluffing about the fingerprints found in the crime scene and assertions about him being spotted on the night of the theft.
Breitwieser, realising the inspector's lies, continues to deny his involvement.
Breitwieser has an idea to let his accomplice stealthily return the stolen bugle, believing it can help him get away. However, he discovers he can't make phone calls as he's a high-security inmate.
Inspector Meier grows suspicious of Breitwieser's composed behaviour and thinks he might be a serial art thief.
Permission is granted to Meier to keep Breitwieser in high-security cells and to carry out an international search of his house in France.
