Husn Bewafa deals with the misdeeds of a straying husband. Rajan (Milind Gunaji) is a successful businessman who totally neglects his wife, Julie (Sangeeta Tiwari). Spurned by her husband, Julie seeks shelter in the arms of Rajan’s friend, Harry. But Harry has some mean friends who not only film him in bed with Julie but also market their love-making through CDs. Ultimately, Rajan comes across the CDs featuring his wife and friend, and repents for not understanding his wife’s physical needs.
