Nadia is a Czeslovakian foreign exchange student who attended East Great Falls during the fall of 1999. She is Jim's love interest in American Pie and American Pie 2. 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 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. 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, does not see the resemblance.
