Murugan is an Indian scientist who has recently discovered how to store a part of the energy unleashed from lightning. He reports this at a Hong Kong scientists' conference. He subsequently announces that he will not reveal his discovery, since the world is at the brink of World War III and his research may be used for destructive purposes. Another scientist, Bairavan, claims Murugan is falsely claiming that his research is successful. Murugan thus conducts a demonstration and destroys the vital research notes, which upsets other scientists. Bairavan offers $100 million to persuade him to sell the research to a foreign country, which Murugan refuses. Murugan then departs with his girlfriend, Vimala for a world tour. He discloses to Vimala that he only pretended to destroy the research notes, and has actually kept them in a safe place. He indeed had plans of using them, to ensure that his research is used for productive purposes. Bairavan, who has been following them, overhears this and plans to steal the research notes. While in Singapore, Bairavan shoots Murugan with a special gun (not killing him). Vimala faints after witnessing the attack. Murugan, who seemingly suffers from a mental disorder, is subsequently taken into Bairavan's custody. Shortly, Vimala too is abducted by Bairavan. He expects her to cure Murugan, so that he could get information on the whereabouts of the research documents. Raju, a CBCID officer and Murugan's younger brother, arrives in Singapore in search of his brother. How he finds his brother and what happens to others forms the rest of the story. Cast

The soundtrack was composed by M. S. Viswanathan. The first choice of Ramachandran for the soundtrack was Kunnakudi Vaidyanathan. Two songs, "Aval Oru Navarasa" and "Nilavu Oru", were originally intended for an shelved film of Ramachandran titled Inaindha Kaigal. Release and reception 
Ulagam Sutrum Valiban was released on 11 May 1973. The film was a major commercial success, and ran for over 200 days in theatres. Ananda Vikatan wrote Ramachandran had already produced great films like Nadodi Mannan and Adimai Penn, but he surpassed them and rose to an unattainable height through this film; viewers could give as many kudos as they want to Ramachandran, who had achieved a great achievement that the Tamil film world could be proud of. In 2005, Mohanlal listed Ulagam Sutram Valiban in his list of top ten best Indian films of all time, stating "I was a kid when I first saw this Tamil film, and I simply loved it. It has all the ingredients needed to entertain people." Accolades
