The trailer of Mammootty's upcoming movie 'Puthiya Niyamam' has been released ahead of the movie's theatrical release this Friday. The trailer gives a gist of the movie. The movie's lead heroine, Nayanthara is introduced first. She is introduced as Vasuki Iyer Louis, who speaks Tamil and is a Kathakali artiste.

Mammootty is introduced as Louis Pothen, an eminent advocate. Martical dischord seems to be the highlight of this movie. Ceratin issues in the life of this couple along with a mysterious crime scene which shows actress Lena as a police officer is glimpsed in the trailer. If cliches have been kept at a minimum, this A K Saajan movie sure will be a winner.
