本片灵感源于芬兰作家朱哈尼·阿霍的小说《牧师的妻子》，讲述了一个发生在当今社会的故事。时至今日，女性仍需扪心自问：是否敢对自己完全诚实？在一段紧张刺激的三角恋中，女主被性冲动引导着去解放真相。

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.

故事讲述在不久的将来，太阳已经变得有毒，人们无法在白天离开家，正常的生活大多在虚拟环境中进行。 在这种反乌托邦背景下，一个垂死的人寻求确保家人的未来幸福，同时应对在这个新现实中成为人的意义。
