Failure of Engineer Garin

Authorities discover the body of engineer Pyotr Garin at an abandoned dacha near Leningrad, and clues point to a murder tied to his heat-ray experiments. The weapon's dangerous potential is underscored by strange traces at the scene. It quickly becomes clear the person found is a substitute, while the real Garin has already escaped overseas.

Investigators confirm the deceased man was Garin's friend posing as him; the real Garin has already escaped overseas to avoid capture. The revelation reorients the case from a murder to a border-spanning pursuit that will draw in multiple powers. The international manhunt for Garin begins in earnest.

The Soviet Academy of Sciences dispatches physicist Shelga to locate Garin and persuade him to return. Shelga must trail Garin across borders, navigating Garin's supporters and rival factions along the way. The mission signals the start of a high-stakes confrontation between science, politics, and power.

Garin finishes his heat ray, a weapon capable of burning through objects at long distances. He envisions using the device to force a new world order and to fund his ascent to power. The invention is simultaneously a scientific triumph and a looming threat.

Garin plots to drill into South America's deep gold reserves to finance his rise to world leadership. He intends to leverage the heat ray to secure wealth and influence before anyone can stop him. The plan draws in international financiers and backers who can turn his dream into reality.

American industrialist Rolling agrees to fund Garin's venture, though he remains skeptical about feasibility and risk. The commitment injects real capital and international momentum into Garin's project. The alliance marks a turning point that makes the heat ray a global issue.

Rolling uses the heat ray to destroy a competitor's chemical plant, demonstrating the weapon's destructive potential. The act proves the device can rewrite industrial power structures and threaten rivals. It also alerts other players that Garin's invention could destabilize markets.

Nazi-aligned factions, and others with stakes in the device, begin secret plots to seize Garin's invention. The heat ray draws the attention of Nazi-aligned factions and other power brokers. Secret plots to steal or co-opt the device begin to unfold. The stage is set for a high-stakes confrontation across continents.

German industrialist Dietz sends his nephew to negotiate with Garin, but the nephew is murdered before any deal can be reached. The killing intensifies distrust and heightens security around Garin. The international chase grows more perilous.

Shelga locates Garin but is gravely wounded in an ambush, delaying the Soviet mission. The assault shows Garin's circle will stop at nothing to protect the device. Shelga's fate hangs in the balance as the manhunt continues.

The Nazis release Shelga, hoping he will reveal the heat ray's location. Shelga recognizes the trap and must decide how to proceed. The pursuit grows more dangerous as multiple factions close in.

Garin invites Shelga aboard his yacht, planning to sail with Rolling and Sheffer to South America. Shelga fails to persuade Garin to abandon his plan or return the device to Russia. The voyage marks a turning point, drawing all parties into a deadly confrontation.

On a volcanic island, Sheffer sabotages the yacht, stranding all aboard. Shelga pleads with Garin to destroy the heat ray, but Garin refuses, nearly killing Shelga in the process. The Nazis close in as the confrontation peaks.

Garin's final use of the heat ray breaks the volcanic crater and unleashes a flood that sweeps everyone into the sea. Only one sailor survives, stumbling onto a shore littered with the dead. The destructive power of the device seals Garin's fate and leaves the world to contend with the aftermath.
