Mario Bonnard - Der goldene Abgrund (1927)

Plot:
An eccentric millionaire brings together four men who, under different circumstances, wanted to commit suicide. The proposal made to them is the following: they will travel to an islet that, according to legend, emerged from the sea when Atlantis sank and that houses a fabulous treasure buried by the Incas. But that territory is populated by the worst band of pirates and evildoers the world has ever known.
