A shy Portuguese poet and an exuberant English occultist meet up in Lisbon in 1930. When the last one disappears, an English detective begins a thorough investigation: was it a suicide, as reported. Or a homicide? This is the real story of the brief meeting between Fernando Pessoa, Aleister Crowley, and Hanni Larissa Jaeger.
Unfortunately the movie Boca do Inferno is not yet available on Paramount Plus.
