Sometimes she is shy and moody, then suddenly she is very direct. Or she remains silent the whole time and later finds the conversation incredibly stimulating. This Marie is truly strange and not the kind of woman one would willingly spend an entire day with. At first, the young student Sarah is just doing her father a favor by showing his important new employee around Vienna – but more and more, she feels a mysterious affection for the reserved Marie. The cheerful, outgoing Sarah makes every effort to connect with the scientist, yet Marie remains inaccessible and introverted – however, she surprises her young companion with unexpected erotic advances. Eventually, Marie reveals to Sarah that she suffers from Asperger's syndrome, a form of autism. Tentatively, Sarah embarks on her first same-sex relationship and experiences thrilling moments.
