Based on a case history, Marijan Vajda's Mosquito der Schaender deals with a young man (Werner Pochath) whose childhood abuse leads him to some pretty twisted behavior. He is shoved around in his small village, causing him to remember being beaten by his father, who also molested his young sister. Now he is a mute who lives alone with a room full of dolls which he habitually destroys, visits hookers whom he disappoints, and generally serves as the town creep. He keeps having incidents with red liquids (ketchup, ink) which he is tempted to suck off his fingers. One day he goes to a mortuary and cuts a female corpse with a knife, drinking her blood and writing "MQ" -- for "Mosquito" -- in blood on the wall. The next day, his mean co-workers give him a blow-up love-doll. It isn't long before Pochath starts hanging around funeral parlors on a regular basis, pulling one corpse's eyes out, decapitating another, and repeatedly stabbing a third. Needless to say, his degeneration begins to accelerate, and soon he steals some glass pipettes from a local store and hallucinates sucking blood out of anatomically correct baby dolls. From there on, the weirdness just accumulates.
