Lucifer is a 2019 Indian Malayalam-language political action thriller film directed by Prithviraj Sukumaran, in his directorial debut, and written by Murali Gopy.

It stars Mohanlal in the titular role, with an ensemble cast consisting of Prithviraj, Manju Warrier, Tovino Thomas, Vivek Oberoi, Indrajith Sukumaran, Sai Kumar, Baiju Santhosh, Kalabhavan Shajohn, Saniya Iyappan, Nyla Usha, Sachin Khedekar, and Fazil.

Principal photography began in July that year and was completed in January 2019, with filming taking place across Kerala in Thiruvananthapuram, Idukki, Ernakulam, and Kollam, along with schedules in Mumbai, Bangalore, Lakshadweep, and Russia.

A message from the CIA is received on his computer, they suspect a diamond-gold nexus is working in tandem with the warlords of Africa and a rear image of a person taken in Istanbul on 7 April 2006 is attached.

Taking advantage of the situation and believing that it would benefit the upcoming election, acting CM Mahesh Varma sends party workers to riot outside the hospital.

Govardhan, a truth-seeker, records a Facebook live stream and condemns those who praise PKR, claiming that he was a puppet, during his final years in the hands of a financial syndicate, which controls the entire Indian political system.

Stephen's past is unknown, but is known for his post-war reconstruction in Iraq and Afghanistan as well as gold smuggling from Dubai to Kerala, which is retrieved from Govardhan's dark web research.

Meanwhile, in Mumbai, Bobby meets his partner, Abdul, and tells him that PKR had given him an ultimatum to stop his drug trafficking a month ago.

On that night, Bobby arrives home, where he gives some Malana cream to Jhanvi, without Priya's knowledge and convenes a meeting with the IUF ministers, informing his decision to fund the party and dissolve the current ministry, which will ensure the preponement of the elections, so that they can take advantage on the present sympathy wave and nominate Jathin as the party's next CM candidate.

Enraged, Bobby assigns Sanjeev, who is the chief of IUF-funded news network NPTV, to start a smear campaign against Stephen, much to the chagrin of his co-worker and wife Arundathi.

From Priya's diary, Bobby finds out that she resents Stephen because her father gave more care for him, who was brought to their home as a child and was the cause for a rift between her parents.

In the mid-credits scene Stephen meets Zayed and his gang in a remote location in Russia and attends a phone call of a gold-diamond trafficker Sanghani, to whom he reveals himself as Khureshi-Ab'ram.
