Chidambara Rahasiyam (2004)

The story revolves around a young journalist Somu, working for Neithal Magazine in Chennai. The company's chief editor, Kumaraguru is like Somu's philosopher. He guides Somu like his own son. Kumaraguru has a daughter, named Thulasi, who is seen acting differently and making origami. Somu and his friend Padmarajan go around Chennai, interviewing people, on a title on previous birth. Once, they meet a beggar and homeless man who says that everything is a line. Somu gets too confused, when the man says he would see an accident on his way back. When the accident really happens, Somu freaks out. The accident claimed a young man's life and a water tanker lorry was the cause of it. To avenge his anger, Somu tarnishes all tanker lorries around Chennai for their reckless driving. Aarthi, a young girl working in Chennai Meteorological Department, is Somu's childhood friend. She is a very talkative girl. Her father is Thillairajan, who is a doctor and he easily believes in all things. Aarthi deduces that Somu would get angry at 4pm the next day, and sure enough he does as his article about the tanker lorry is not published as expected. Kumaraguru says to Somu that he is hasty in everything and need patience. Somu realized that the victim of the accident is getting married soon. He together with Padmarajan, got to the victim's fiancée home, only with his father-in-law's identity. The man happened to be a Tamil teacher (Tamil vathiyar). But when Somu and Padmarajan go there, they realize that the man and his daughter had both died. Somu finds the home ransacked and that someone has taken the guy's fingerprint. When Somu confines in Kumaraguru, he tells Somu about Nadi Josiyam. Nadi Josiyam is a type of method to find our future through astrology, with the help of the person's thumb impression and some palm-leaf manuscripts. Somu goes and meets a nadi josiyar, with the accident victim's thumb print. The nadi josiyar, Ponnambalam, refuses to further read it as the man is dead. On Somu's request to trust nadi josiyam, the nadi josiyar asks him to take a living man's fingerprint and see him tomorrow. Somu then takes the finger print of the beggar. The beggar then dies after fainting on the road side. The next day, together with Aarthi, Somu goes to meet Ponnambalam to find him dead. Aarthi finds that someone took his fingerprint. She does too and they go to meet another nadi josiyar, Anbarasu. Anbarasu tells Somu that someone came with the man's fingerprint and took away the manuscript. Meanwhile, an NRI from America, Akash, comes to Chidambaram to visit his grandmother. He works in a company that provides bio metric security systems. Aarthi's meteorological department had requested the company to provide security systems to their company. Akash has a strong American accent, which makes his Tamil to sound very different. He stays with his grandmother for his holidays, when his cousin Abhirami comes to stay there as well. Abhirami's aunt, who by right should have been married to Akash's father, is suffering from Leukemia. Akash quickly gets interested in Nadi Josiyam after meeting their neighbour, Nadi Josiyar Mani. Akash's grandmother Visalakshi gives him an old manuscript done by her father-in-law, to Akash which excites him. Visalakshi soon regrets her act when the boy gets too interested in it. Meanwhile, Aarthi sends her sister Archana's barathanatiyam dance instructor to Somu's office for an interview, much to Somu's annoyance. Irritated, he asks the man to go home and that he would meet him there the next day. But when he goes there with Padmarajan, the instructor, Natesan Sharma, dies after falling down from his flat. Somu sees that his thumbprint is taken as well and also sees a church father there. AC Adiyapatham investigates all these cases, including Tamil Vathiyar's and starts suspecting Somu, as he is seen at all crime scenes. Akash brings the manuscript that, he and his grandmother thought to be his, to Mani. Mani then says that the manuscript belongs to someone called Someshwaran. When he confines in his grandmother, he realizes that he has no relatives named Someshwaran and that there is only one retarded 10-year-old boy called Somu, in that street. Visalakshi asks Akash to leave all the things about manuscripts. His grandmother then hides the manuscript but Abhirami gives it to him secretly and he leaves for Chennai. Somu and Akash's colleague, Ismail gets into a quarrel when Ismail accidentally damages bike. Somu then goes to Ismail's office, when Akash is also, to get compensation. He later finds Ismail dead in the toilet, with the church father being the last one to leave it. AC Adiyapatham then tries to arrest Somu as he is seen there. Kumaraguru brings Somu to his guesthouse, on Chennai's outskirts. Meanwhile, Thillairajan blindly starts trusting a astrologer who tells him that he would not see Aarthi again. Fearing that something would happen to Aarthi, he locks her inside their home and plans to get Somu and Aarthi married. Aarthi, in the name of helping Somu.
