Surya, a juvenile offender, completes his education in prison and upon release embarks on his dream project. However, he has to overcome numerous obstacles to turn his dream into a reality.

Surya has a rare genetic disorder that is deadly if he is exposed to sunlight. To prevent this from happening, Surya lives his life by night. When he falls in love with Sanjana, things become complicated for them both.

Based in Kancheepuram, Surya/Arjun makes a living as a con-man on the North Zone, and is assisted by his girlfriend, Baby; while the South side is presided over by Pashupati. When a Kolkata-based contractor hires the latter to kill District Collector Jaianand/Kishan, Surya decides to defend him - this results in his finding out that Jaianand is his look-alike. Jaianand's terrified fiancée, Shanupriya, then hires Surya to not only protect but also impersonate Jaianand - a move that will drastically change everyone's lives - especially when Kishan refuses to let anyone take his place
