由于梦想与现实之间的界线越来越模糊，一位雄心勃勃的教授陷入了谋杀一名睡眠研究参与者的困境。

Despite qualifying for armed force, Karthik ('Jayam ' Ravi) prefers to be a traffic cop in Ooty as he believes that such a no risky job would help him get enough time to look after his cute little sister Vidhya (Baby Anikha). Karthik also has a short lived one side love story with Renu (Lakshmi Menon), who is a doctor. When a hazardous chemical in the nearby industry gets leaked, a dog consumes it and turns into a zombie. As the dog bites a watchman, he too becomes a zombie and eventually, the virus spreads rapidly across the town. Can Karthik save his sister and the city ?

此电影翻拍自北印度2009年的由阿米尔汗主演的火爆全球，正在中国上映的《3 Idiots》。 电影以两个好朋友Venkatramakrishnan，Sevalkodi Senthil在寻找多年不见的老朋友Panchavan Parivendan aka Pari的过程中展开回忆。Srivatsan是该部影片的反派角色，虚伪，功利，心眼不好。电影通过断断续续的倒序画面向我们讲述了Pari的故事。Pari是名聪明而又不拘小节的学生，他不随波逐流，特立独行，以自己的魅力成功影响了他的两个好朋友，帮助他们找到了自我，学会去追逐自己的心，抱着笑面吟诵Pari的名言“一切皆好（all is well）”的心态面对生活。Pari敢于对教育体制说不，经常打破陈规，与校长Virumandi Santhanam教授的名言“生活就是场比赛，加油去跑（Life is a rce-Run Run Run）对着干。最终他赢得了Virumandi女儿Riya的芳心。该影片通过回忆讲述了Pari传奇的一生。
