Anniyan is the story of Ramanujam Ambi Iyengar (Vikram), a lawyer who suffers from Multiple Personality Disorder. Ambi is an innocent and honest lawyer. If he comes across anyone not obeying the rules he files cases against them but all his efforts go in vain.　　His constant habit to be perfect in rules and honesty leads him to develop a Multiple Personality Disorder in which a new character in him grows as Anniyan (Vikram) and starts a website called to hear people's complaints. The new character, Anniyan, is a violent man. When he is Ambi and comes across a person who does not obey rules he makes complaints in his website. When he is Anniyan, he goes and kills them by methods used for torturing people in hell. He apparently takes the definition of these methods from the Garuda Purana.

The film is a unique social comedy based in a small town of Uttar Pradesh directed by Hansal Mehta.

这影片原是Fox拍摄的一部美剧的试播集，但FOX最终决定将其拍摄为为一部80分钟的电影在netflix上首映。作为电影可能挖了太多天坑，但一个男人通过一座神秘建筑进入无限的平行宇宙，遇到无限个的自己的故事很绝。
