Lars and his serious boyfriend - DVD

Lars is a typical looser, lives in a small town and is touchingly shy. One day, he brings his new girlfriend - a blow-up doll called Bianca, ordered over the internet - to his brother and his wife's house. But instead of sex, Lars craves a real and affectionate relationship, and he treats Bianca accordingly.
But how to explain this to the inhabitants of a small town? Fortunately, everyone likes Lars and soon Bianca is attending church, working as a maid in a dress shop and volunteering at the local hospital. Lars may find his surroundings sympathetic.
