Ebin(Tovino) and Madhavi(Keerthy) are two aspiring lawyers and are in love with each other. Ebin is from a rich and influential Christian family and madhavi is from a middle class hindu family with only her mother. Ebin, with the influence of his brother in law Jose(Rony) is appointed as a public prosecutor. Ebin is first assigned a case of a girl anusha by her father who files a case against her colleague gautham for having sex with her with the promise of marrying her and later cheating her. Its madhavi who appears for gautham since they are childhood friends. For ebin, its his first case as public prosecutor and a prestige issue. On the other hand for madhavi its her family friend. Hence both can't withdraw from this case. On top of that, due to family pressure both have to get married while this case is going on. How this case take a toll on their married life and whether they can live happily keeping their professional differences aside is the rest of the movie.
Vaashi has an interesting plot backed by decent performances from tovino and keerthy. But it suffers from extremely mediocre direction and production values. Script tries to be on a safe zone and the courtroom is not hardhitting.
