Shari Wilson is living in the same apartment as a sexy journalist named Luke Lawson. But no matter how fashionable her clothes, he doesn't seem interested in asking her out on a date. One day she accidentally sees a book that he ordered. Lo and behold, the title of the book is The Idiot's Guide to Sex! To her surprise and amusement, despite his cool and handsome looks, he is so inept at pleasing women he needs a how-to manual. But the book is only the beginning of Luke's sexual education, and soon Shari agrees to help him with the guidebook's practice lessons!
