M
There have been a rash of child abductions and murders in Berlin. The murderer lures the children into his confidence by candy and other such child friendly items. Everyone is on edge because the murderer has not been caught. The most substantial pieces of evidence the police have are hand written letters by the murderer which he sent to the newspaper for publication. Unknown even to himself, a blind beggar, who sold the murderer a balloon for one of the child victims, may have key information as to the murderer's identity. The murder squad's work is made even more difficult with the large number of tips they receive from the paranoid public, who are quick to accuse anyone of suspicious activity solely for their own piece of mind that someone - anyone - is apprehended for the heinous crimes. Conversely, many want to take the case into their own hands, including the town's leading criminals since the increased police presence has placed a strain on their ability to conduct criminal activity. Although they both have the same end goal of capturing the murderer, the police and the criminals seem to be working at cross purposes, which may provide an edge to the murderer in getting away.
The film earned $35K at the global box office.

Plot Points by Act
Act I
SetupStatus Quo
A mother waits for her daughter Elsie who never returns home from school, establishing a city gripped by fear of a child murderer. Her calls echo through an empty stairwell—the child's ball rolls from bushes, her balloon caught in telephone wires.
Theme
A police official states: "We must find the murderer before the public takes the law into their own hands." The film explores justice versus mob rule, and whether society's pursuit of monsters makes them monstrous.
Worldbuilding
The city's dual response unfolds: police conduct massive raids and investigations while the criminal underworld suffers under increased scrutiny. Citizens turn paranoid, accusing innocent men. The killer remains unknown, leaving only chalk marks and whistled tunes.
Disruption
The crime bosses convene an emergency meeting as police raids devastate their operations. They cannot conduct business while the city is in upheaval. They decide they must find the killer themselves to restore order.
Resistance
Parallel investigations develop: police use forensic analysis and handwriting experts while the underworld organizes beggars as a surveillance network. The police narrow suspects through methodical detective work. The underworld prepares to hunt using the city's invisible eyes.
Act II
ConfrontationFirst Threshold
Hans Beckert encounters another potential victim. A blind balloon seller hears him whistling Grieg's "In the Hall of the Mountain King." The criminal underground's network activates—Beckert is marked with chalk "M" on his back, transforming from invisible predator to hunted prey.
Mirror World
The beggars and criminals become the film's conscience—outcasts and lawbreakers acting as protectors of children. They represent society's shadow, revealing that traditional morality is inadequate against incomprehensible evil.
Premise
The hunt intensifies as both police and criminals close in. Beckert, unaware of the "M" on his coat, moves through the city while being tracked. The premise delivers: can Berlin's criminal class succeed where law enforcement has failed?
Midpoint
Beckert discovers the "M" marked on his back in a shop window reflection—he realizes he's been exposed and identified. The hunter becomes hunted. False defeat: he's still free but now knows they're coming.
Opposition
Beckert flees in panic, hiding in an office building as criminals break in to find him. The building is locked down. Police discover the break-in and surround the building. Beckert is trapped between two forms of justice—legal and extralegal.
Collapse
The criminals discover Beckert cowering in the attic, dragging him from his hiding place. He is captured, stripped of freedom and identity. The "whiff of death": his social death as he faces mob judgment.
Crisis
Beckert is taken to an abandoned distillery for an underground kangaroo court. He sits in darkness, surrounded by criminals who despise him. Even murderers and thieves find him beneath contempt. The trial begins.
Act III
ResolutionSecond Threshold
Beckert is given a defense attorney from among the criminals. The trial will proceed with structure and argument—civilization's forms imposed on mob justice. The question shifts from "is he guilty?" to "who has the right to judge?"
Synthesis
Beckert delivers an anguished confession: he cannot control his compulsion, pursued by the ghosts of his victims, driven by voices he cannot silence. He begs for mercy as someone sick, not evil. The mob demands execution. Police burst in before the verdict.
Transformation
Mothers of victims sit in the courtroom as the legal verdict is pronounced offscreen. One mother says, "One has to keep closer watch over the children." The cycle continues—no justice satisfies, no punishment restores. The image of collective grief replaces individual resolution.
