The film stars Prashanth and Pandiarajan, while Vadivelu, Ankitha, Mumtaj, Vijaykumar and Srividya play supporting roles.

Shiva Raman, an easy-going young man from Chennai, comes to London in search of a job, but he loses all of his certificates.

Meanwhile, to find a safe cover, Shiva and Kathir plan to imitate Saravanan, the grandson of a rich elderly couple: Rajasekar and his wife Parvathi.

Ganesh, who knows Kathir before, makes several attempts to expose the truth to the couple, but all fail, due to Shiva and Kadhir's luck.

Amidst their drama, Kathir tries to steal the Lord Muruga statue, for which he plays a trick to injure Parvathi, which keeps all others out of the house for sometime.

Rajasekar asks them to continue the drama for the sake of his wife, who loves her grandson more than her life.
