She is Jim's love interest in American Pie and American Pie 2. In American Pie, Jim tries to lose his virginity with her. He tries to make it seem as if it is a study group. We see that she has a type of sex drive in the first film, along with being tall, sexy and having nice figure. When Jim tries to find a girl to lose his virginity to, she asks to try and help with her studies. Knowing that he could use this advantage to have sex with her, he told her that they could start tomorrow. The problem was that she had ballet practice after school, but she asked if she could change clothes in his room, which instantly agreed to. When she meets him at his house after her ballet practice. He tells her to go change in his room while he'd get something. He tried to peek at her with his friends on webcam.
There she stripped half naked, only wearing her panties. When she finds his porn magazine, she masturbates to it and lost attention to her surroundings. Jim ran back to his house to make a move. When he snuck in, he tried to make a one liner, but she was embarrassed. At first she was mad, but then she told him to return the favor by stripping himself. Jim did as he was told, and when he did she found him kinky. She then asks him to sit on the bed. She tries to get his hand into her panties, but he prematurely ejaculates. She then loses interest, and decides to dress up. He then tries to tell her that he still can have sex, and brings out his porn collection. He starts to show it to her, but says that none of them were as beautiful as her (dam right). She then thanks him for the compliment, by laying on him and rubbing up against him. When she is about to deflower him, she took off her panties showing Jim her front. The sight of her shaved vagina causes Jim to again ejaculate prematurely. It is assumed that she leaves after this. However, her exchange family saw this webcam video, and sent back to Central Europe. At the end of the movie, it is shown that she and Jim still like each other, and Jim tries to strip to make her horny. His father sees this, but just goes with the flow.
At the end of American Pie 2 when Jim chooses Michelle over her, she is sad and hurt but then meets Chuck "Sherminator" Sherman and develops an instant sexual lust for him and drags him upstairs to have sex. The next morning, she is seen in bed cuddling with him. It is unknown what happens to their relationship after that, but it can be assumed that it was a one night stand as Sherman, with no meaning, as he later married and divorced someone else.
She is absent in American Wedding but is mentioned and is the topic of a conversation between Jim and his father. Jim asks if he could sleep with her, would he? HE replies, "In a heartbeat". She makes a brief cameo in the ending moments of American Reunion, with a new boyfriend (or possibly husband) named Mitch, who is short in stature and looks an awful lot like Jim. Mitch, however, she does not see the resemblance.
