Christian O'Connell (Ivan Sergei) has met the girl of his dreams in Alison Marks (Jennifer Love
Hewitt). Unfortunately, Christian told Alison (who happens to be a rabbi’s daughter) that his name was Avi Rosenberg, and that he was Jewish- neither of which are true. Desperate to keep up the illusion, he turns to his childhood best friend, Adam Lipschitz (Joel David Moore) to teach him how to "act Jewish." But Adam has problems of his own, with a fiancé (Jamie-Lynn Sigler) pushing him closer to a mental breakdown as their wedding approaches. With the best intentions, Adam and Christian attempt to help each other out.
