24 is a 2016 Indian Tamil-language science fiction action film written and directed by Vikram Kumar. Based on the concept of time travel, the film stars Suriya in a triple role alongside Samantha Ruth Prabhu and Nithya Menen. In the film, Sethuraman, a scientist invents a time traveler watch which leads to a bitter battle between his evil twin brother Athreya and his lookalike son Mani in the future.


Sethuraman is a brilliant scientist and renowned watchmaker who lives with his wife Priya and newborn son Manikandan. He has devoted himself to inventing a time machine using a watch. On 13 January 1990, Sethuraman manages to successfully complete his invention, although it is only capable of moving back and forth in time for 24 hours. His happiness is short-lived, however, as his evil twin brother Athreya attacks the family and kills Priya to get the watch. He manages to find the key to the box that the watch was hidden in, but not the box. Unable to use the watch and fearful for his son's life, an injured Sethuraman manages to escape with his son and gets on a train, with Athreya in close pursuit. Sethuraman pleads with a woman he meets on the train named Sathyabhama to take care of his son and goes to face Athreya. He manages to trick Athreya into thinking he is carrying a bomb, prompting Athreya to quickly kill Sethuraman before jumping off the train to his apparent death.
