Kuchh Luv Jaisa is a story about a house wife, Madhu (Shefali Shah), who gets ditched by her husband (Sumit Raghavan) and kids on her birthday which happens to come once in four years, Feb 29. Now Madhu is left with two options as she can either choose to sit at home and sulk, pity herself for the next four years or reinvent her boring, mundane life into an exciting one and take a grip over it. She eventually decides to head out and enjoy her birthday according to her whims and fancies. She splurges her husband’s money in an unusual way. She shops for clothes, gets a makeover at an expensive parlour and above all buys a car! It is an unusually fun filled day for her until she meets Raghav (Rahul Bose), a criminal on the run who is trying to mingle with the ‘normal’ crowd posing as an undercover agent so that he can escape the cops. A ditzy and happy-go-lucky Madhu runs into Raghav at a coffee shop where he is planning his next move and in this process a casual conversation begins. Mistaking him for a detective she requests him to be a part of one of his cases only for a day and from this Raghav takes his cue. He continues to pretend that he is one! With this begins a day-long adventure of the duo which changes their lives forever.
