两位帅哥索努(卡提克·雅利安饰)和提图(桑尼·辛格饰)是从小在一个屋檐下长大的好友,但两人性格迥异。索努机灵果断,是单身贵族;提图温柔善良,易被女孩子诱骗,而关键时刻将掉进坑里的提图拯救出来的永远都是索努。忽然一天提图决定和斯维蒂(努什拉特·巴茹查饰)结婚,在提图眼中,斯维蒂花容月貌,是个完美的女孩子;在索努眼中,斯维蒂八面玲珑,是个不怀好意的心机婊。于是,索努请来提图的前女友皮胡(伊西塔·雷饰)来共同搅局,而提图面临着要在好友和女友中二选一的局面,最后会鹿死谁手呢?We have always been told that "Marriage" is a marriage between two families. 'Sonu ke Titu ki Sweety' explores the new age version of the same belief where "Marriage" is a marriage between two friend circles. What happens when you decide to get married, but your best friend and your girlfriend can't see eye to eye. Sonu and Titu are childhood friends. Titu has always been a naïve lover, who falls in love easily and Sonu has always had to step in to save him. But Sweety is the perfect bride and Titu is head over heels in love with her. Sonu's instinct to protect Titu at whatever cost, makes him feel that she's too good to be true. What ensues is a war between the best friend and the bride to be. While Sweety is trying to impress Titu and the family alike, Sonu is out to sabotage the utopian romance.
