Karl, Vera´s boyfriend, sends our beloved Heidi to walk the streets. And it seems as if Heidi has a lot of fun with that. But very soon her stepgrandfather and the "goat-Willy" are on their way to Munich to save Heidi from the sink of iniquity. But what the two guys find out at the Sennemann´s mansion, even goes over their imagination. Each person fucks with each other and in front of all that: step-aunt Grete. Heidi gets saved and as she is back on her alps, she starts to fuck on and on again with a smile on her face. With Tanja Fielmann as the always-horny Heidi Directed by: Juergen Baumann
