Thoongaa Vanam is a 2015 Tamil crime thriller starring Kamala Hasan in the lead role and supported by Prakash Raj, Not sure about the role by Trisha. The film is an adaptation of the 2011 French film Sleepless Night (French: Nuit Blanche).
Normally Tamil crime thrillers tends to be sloppy and sentimental. I found this is different. It involves drug, drug barons, kidnapping and rescue. Gripping movie keeping you interested. Kamala Hasan has underplayed the role and makes it realistic and close to the original.
Rating: PG (Drug, Adult themes and scenes)
