Companionship, togetherness, love marriage; the phrase "Life Partner" has different connotations for different people. There is someone made for everyone, including Karan, Bhavesh and Jeet. Karan and Sanjana are madly in love with each other. Marriage is the next step to cement their relationship. But, is "love marriage" the right way to be? For Bhavesh, his life partner, Prachi comes with the approval of his family. But, is "arranged marriage" the way forward? Is it right to prioritize family over marriage? Does Prachi have to prove herself as a worthy daughter-in-law to qualify as an ideal wife? Jeet is an accomplished divorce lawyer who does not believe in the institution of marriage. He can't be monogamous and is often responsible for his getting his clients divorced. But, is "no marriage" the right policy? Will Jeet ever find a partner and accept matrimony? "Life Partner" is about three protagonists struggling on the marital marathon but on different tracks -- three good friends with three different approaches to life.
