12:15 AM, Room 9

During a routine experiment the young hotel manager rigs a transmitter in the room of his fiancée Maria. The setup accidentally uncovers a plot by counterfeiters who plan to eliminate a troublesome witness at 12:15 AM. As tension tightens in the quiet corridors the manager scrambles to thwart the scheme while wondering if the woman he loves can be trusted. Behind the polished surfaces of the hotel cheats, swindlers, forgers and murderers blend with respectable guests, turning the lobby into a chessboard of suspicion where every glance may hide a motive. The clock ticks toward a dangerous midnight and one false move could prove fatal. The film relies on restrained performances and claustrophobic space to carry suspense.

Directed by Arthur Maria Rabenalt and released in 1950, this German crime picture shows a tense hotel atmosphere and a plot rooted in postwar anxieties; it explores how respectable surroundings can hide danger, while leaving the exact source material open to interpretation.

Box office data for this title isn't readily available in standard databases. As a mid century release, its commercial footprint appears modest and largely undocumented outside of archival film records. Its modest profile suggests it held local appeal rather than international fame today.

Reception likely emphasizes the looming dread created by a routine setting turned risky stage. The script leans on ambiguity around trust and loyalty, using crowding and watchful glances to probe how appearances hide motive in a hotel world where everybody wears a mask, even friends.

As a mid century crime thriller, this title falls into the quieter end of its era. It neither sparked a major film noir wave nor produced memorable lines, but it offers a brisk puzzle feel and a snapshot of hotel life as a microcosm of postwar uncertainty, with clean lighting and crisp pacing.
