Mamantula is the guy everyone wants, but he is also, secretly, a giant tarantula cross-dressing as a human, spawned during a brief encounter in a distant paradise.
In an alternative present of brutalist saunas, endless underground corridors and detectives wearing trench coats and hats, each of Mamantula’s lovers falls victim to his insatiable lust for blood and semen; one more thread in the stellar spider’s web he is weaving to return to the dimension where he belongs.
