One night in December 1995, 4 tons of weapons fall from the sky over India. A few days later a Danish man returns to Denmark with a grave secret. Only when an English arms dealer is arrested in India and faces death sentence, does the Dane appear in the large-scale international investigation of the case. With reconstructions and scenes resembling a feature film, the docu-thriller The Arms Drop tells the nerve-racking story of two men who gamble their lives on a joint mission with each their secret agenda, and the political, personal and diplomatic consequences 20 years later.
