There is an author who has been dumped by his girlfriend and has no inspiration for a next novel. In an attempt to find a solution to both crises, he, along with his publisher friend, decides to seduce a young woman with the singular purpose of keeping a diary of the seduction and then dump her before publishing the book about it. Unfortunately he falls in love with her.
After saving each other from jumping off a bridge, Henry Bell and Karen Knightly plot to avenge the people who drove them to suicide. Henry will ruin the life of the woman who married Karen's boyfriend, while Karen will work as a secretary for the man who took Henry's job.
