The story takes off when Nadiya, who is settled in Bangkok, brings her daughter down to Coimbatore to get married to another NRI. But strange happenings, a few failed kidnapping attempts, and one which is finally successful -where Nadiya’s daughter is taken hostage - followed by a surprising turn of events and a few threats later, the groom and the family withdraw from the marriage leaving Nadiya in a lurch. In a split second decision she asks Sundar C (her bodyguard) to take the groom’s place, only to realize she has blindly walked into a plan that was cleverly set down by her elder brother played by Lalu Alex (Malayalam actor). The rest of the story revolves around the clashes between the son-in-law and mother-in law, her clever plans to prove to her daughter that Sundar C is not a man worthy of her and his fitting replies to all her schemes. Namitha appears in one such scheme where Nadiya wants to prove Sundar C’s infidelity. Namitha as usual has been used to raise the glamour quotient and she does what is required of her (she is becoming something of a constant in Shakthi Chidambaram’s movies).

Sandai isn’t much of a movie, but it doesn’t bore you at any point either. Vivek’s double act comedy track raises a few laughs, generally rising above the rather ordinary form that he has been showing off late.
