Steve is asked by Oscar Goldman to escort pert gymnast Tanya Breski, star of the touring Soviet troupe, during her stay in the United States. Steve's assignment turns out to be a tough one; he must deal tactfully with Tanya, who develops a schoolgirl crush on him and wants to defect, while protecting her from a subversive group which plots to do away with her--putting the blame on the United States and thus badly damaging US-USSR relations.
