A lot of the events in 24 happen mainly on account of accidents and coincidences, but it is to Vikram Kumar’s credit that we buy into those scenes so willfully in this novel and entertaining, but definitely over-long, film that constantly charms us or leaves us thrilled with its inventiveness. The film begins with one such accident when an eagle acts a catalyst for Dr Sethuraman’s(Suriya) invention — a time machine. He is a famed watchmaker and inventor, living contentedly with his wife Priya(Nithya Menen) and their son. But his look-alike twin brother Athreya is smarting at his success and plans to have the time machine, which is in the form of a watch, for himself. But Sethuraman manages to save both his son and his invention by giving up his own life.
Cut to 26 years later, and the baby has grown up to become Mani(Suriya, again!), a watchmaker, raised by Sathyabama(Saranya Ponvannan in yet another enthu-mom roles). Mani is oblivious to his past, but, by a quirk of fate, he discovers the watch, and over a scene that is a wonderful a piece of movie magic(involving droplets of rain), discovers its power. He uses it to woo Sathya(Samantha), a girl who turns up at his store to get her watch repaired — or rather makes her fall in love with him with help from the device. This is the film’s light-hearted stretch and Vikram Kumar keeps throwing at us the possibilities that such a time machine offers. One such possibility, a Quicksilver-like ability to freeze time, even involves affecting the outcome of a cricket match! But the romantic portion in the second half is definitely a drag and the situation is made worse by a visually cliched song that has the leads walking around in picture postcard-esque locations. It effectively acts as a second interval.
Meanwhile, Athreya, who has been in coma all these years, regains consciousness(again, this happens by accident and involves an eagle!), and finds himself having aged and paralysed waist down. But with the help of his trusted aide, Mithran tracks down both the watch and Mani and plots to get the device in his hands and go back into the past to rewrite his destiny.
It has been a while since we had a film whose twists and double twists were genuinely surprising and in 24, we are kept slightly off-guard as to what might happen when a character does something. Vikram Kumar doesn’t sacrifice the internal logic of the story, so the twists always seem plausible and surprising. Like in the climax, when Mani decides to save his parents by time-travelling to the day they were murdered, and how that pans out. He also balances the sci-fi/fantasy elements with a melodramatic sub-plot, involving Sathyabama, Mani and her estranged family, which invokes the’amma sentiment’ and acts as an unabashed sop for the’family audiences’.
