The Finnish listening station on Kallbåda records under water explosions 14th September 1942. Lieutenant Erkki Palosuo’s Tupolev SB-10 naval bomber is soon sent to find the cause.

Meanwhile on the Gulf of Finland, a Soviet submarine crew is working desperately. Their boat has hit German anti-submarine mines. The explosions have not been powerful enough to sink the submersible, but they have caused considerable damage. The boat is totally exposed.

Palosuo’s bomber reaches the area. Machine gunner Kalle Ahvensalmi soon spots a submarine, which is making an emergency dive. Palosuo drops the depth charges, presumably sinking the submersible.

But what happened next? Mikhail Ivanov tells in this 15 minute webisode the whole story of Kumzha.
