Raman Raghav 2.0 (released internationally as Psycho Raman ) is not a traditional biopic of the 1960s Mumbai serial killer. Instead, it is a contemporary "cat-and-mouse" thriller that presents a terrifying mirror image between a remorseless murderer, Ramanna (played by Nawazuddin Siddiqui ), and a corrupt, drug-addicted police officer, Raghavan (played by Vicky Kaushal ).
