Frank, a tour guide, has an innately charming way with the opposite sex, and the generous desire to help out his less accomplished roommate improve his love life. When the roommate falls for an attractive psychiatrist, the tour guide manages to get in to see her, hoping to insinuate his roommate into her affections. His altruistic objective dies when he actually meets her and is smitten himself - and then the task that lies ahead is how to keep on seeing her and beguile her into sharing his feelings.
