The movie starts off with a hotel, where a gunshot was heard and immediately the police arrived. It stops there and immediately shifts to the main lead, Aryan. Aryan is a Narcotics Control Bureau Officer who works alongside his batchmates Sathya and Varun. Aryan lost his twin Brother, Dillip, to drugs, therefore he becomes a Narcotics Officer and his main aim is to eradicate all drug groups and drug lords, known as the ‘Snake’s Den’. Alongside his team are Selvam, his team supervisor and Mugilan, a social activist who is also Aryan’s neighbour. Whilst Aryan arrives home after catching two culprits that were into drugs, he receives news that Selvam has died due to a gunshot at the head. Previously, Selvam had concluded the guy behind this, but did not reveal so the culprit wouldn’t know about this. Aryan and Sathya investigate around the house, and Aryan concludes that there is a big drug lord behind the murder, and they must find evidence of that. Mafia 2020 full Movie
Mugilan is also targeted by the drug lord and his bodyguard and is killed. Before his death, he puts information about the drug lord in a USB stick, attached to his dog, Pogo’s collar and sends Aryan a message. Aryan tracks Pogo down with the tracking chip installed in his collar and sees the information. The drug lord is apparently Diwakar Kumaran (DK) who is a big technology entrepreneur and a philanthropist. Mugilan suspects his early source of income was with links of international drug cartels. DK and his brother/bodyguard Rudra have links with politicians, so their business cannot be derailed. Knowing this Mugilan and Selvam decides to investigate a place thought to be Diwakar’s secret hideout. Through this they were both caught.
Aryan later moved on to start a shootout at the place, and finally concludes Diwakar’s role in drug dealing. DK, knowing what will happen, abducts Aryan’s family and asks Aryan to meet his doom at a warehouse.
