SAVI is the story of a woman trying to save her husband. Savi Sachdev (Divya Khossla) is a homemaker who resides in Liverpool with her husband Nakul Sachdev (Harshvardhan Rane), who works in a construction company, and son Adi (Mairaj Kakkar). Life is going fine until one day, Nakul is... arrested by DI Ayesha Hassan (Himanshi Choudhry) for the murder of his boss, Stefani Fowler. Nakul pleads to the cops that he’s innocent. However, the evidence against him is tremendous. Stefani had humiliated Nakul in the past and this gave the latter a solid motive. Secondly, Stefani was killed after being hit with a fire extinguisher. Nakul’s fingerprints are found on the extinguisher. Also, his coat has blood stains, that belong to Stefani. The court awards him a life sentence. Savi’s life comes crashing down. Meanwhile, Nakul gets into trouble in Shrewsbury Prison. A notorious gangster, Razaq, asks Nakul to keep a packet of drugs safe. Nakul is beaten up when he refuses to do so. Razaq is kept in solitary confinement but only for a month. Nakul is hospitalized and files a complaint against Razaq for the assault. Razaq’s man warns Nakul to take back the complaint; or else, Razaq will teach him a lesson once he’s out of solitary confinement in three days. Nakul refuses to bow down. This is when Savi decides to get her husband out of jail. While researching prison breaks, she comes across the book written by Joydeep Paul (Anil Kapoor). He has escaped from jail a record seven times! Savi tries to meet him to get tips. But Joydeep is extremely reclusive. What happens next forms the rest of the film.
