Marcus is a successful advertising executive who woos and beds women almost at will. After a company merger he finds that his new boss, the ravishing Jacqueline, is treating him in exactly the same way. Completely traumatized by this, his work goes badly downhill. But then Jacqueline’s more quietly attractive assistant Angela, who has been dating Marcus’ best friend, shows herself more than a little concerned by his parlous state. —IMDb
