Under lock and key - a Bernese political thriller

Berne, April 1990 - The cache scandal keeps the country on tenterhooks and rumours about the existence of a "Swiss secret army" intensify. In the midst of this heated atmosphere, a murder case shakes the federal capital. The fast-paced theatre tour through Marzili treads a fine line between reality and fiction. On the trail of the resistance organisation P-26, the audience is immersed in the incredible story of anonymous messages, explosive lists of names and dead letterboxes.

The starting point is the murder of Lieutenant Colonel Herbert Alboth, who was found dead in his flat in Bern. The case remains unsolved to this day. The many unanswered questions leave room for speculation: Why did he have to die? Is the P-26 involved in the murder? Or was it a relationship offence? Bene Grüter from the press comes into possession of a mysterious briefcase. It soon becomes clear that it contains explosive information - perhaps even the key to the murder of Herbert Alboth? The investigation opens up unexpected abysses.
