In the heart of Germany, a young, brunette hitchhiker named Karin flags down a passing car, driven by the lecherous Reinhard, a grandfather with a penchant for young flesh. He takes her on a joyride through the countryside, his eyes constantly wandering to her perky breasts and tight teen body. Karin, enjoying the power she holds over him, teasingly asks, "What do you want, Opa?" Reinhard, unable to resist her playful advances, pulls over, ready to give the young Deutsche tramperin a wild, public fuck she won't soon forget.
