A plane leaving the turmoil of a South American country in the midst of a revolution crash-lands in the Amazon jungle in Brazil. Among the passengers are a corrupt banker who is smuggling diamonds out of the country, a reporter, a mysterious beauty and a shady flight attendant. The survivors find themselves up against not only the dangers of the jungle itself but a band of headhunters and a gang of revolutionaries who are looking for the smuggled diamonds.
Unfortunately the movie X312 - Flight to Hell is not yet available on HBO Max.
