The Unfinished Supper (Russian: Незаконченный ужин, Latvian: Nepabeigtās vakariņas) is a 1979 Soviet police film about Martin Beck,[1] directed by Jānis Streičs, based on the novel Murder at the Savoy (1970).
[2] At a banquet in the "Savoy" restaurant, which resembles a café, a prominent Swedish businessman and head of the Palmgren conglomerate is murdered.
As the investigation progresses, it becomes increasingly evident that the true cause of the tragedy lies in state-level corruption, implicating a powerful governmental mafia.
Throughout the case, both the police and SEPO inspectors behave rudely, frequently drinking beer and refusing to show identification.
Despite these challenges, the team eventually identifies the murderer as Berthold Svensson, an unemployed former employee of Palmgren's conglomerate.
