Random people in Bengaluru are kidnapped and brutally killed by a serial killer (Anurag Kashyap). The killer claims to be Rudra, the same serial killer allegedly shot dead by CBI officer Anjali (Nayantara), some years ago.
A genius hacker who leaves no traces of his whereabouts, Rudra taunts Anjali to stop the killings. Meanwhile, Anjali's brother Arjun (Atharvaa) is still recovering from a breakup with Krithika (Raashi Khanna). Unknown to Anjali, Arjun and Krithika, Rudra has devilish plans for the three.
Imaikkaa Nodigal has a plot with convincing twists and a show-stealing performance by Anurag Kashyap (voice dubbed by Tamil director Magizh Thirumeni). Nayantara is good, Atharvaa and Raashi Khanna play their supporting acts sportingly. The mercurial Vijay Sethupathi is damn good in a short cameo.
The makers are guilty of abandoning logic and believability at times, as many Tamil mainstream movies do so often. Songs mar the pace, add no layers to the story.
The razor-sharp editing and the lead performances ensure that Imaikkaa Nodigal (Blinkless Seconds) holds together as an emotionally exploitative mass audience targeted crime thriller.
If Imaikkaa Nodigal is worth a one-time watch, the bearably sane and not too obvious storytelling and screenplay by director R. Ajay Gnanamuthu is a factor too.
