Rumor

When the foundation-laying ceremony of a highway project unearths a skeleton, all hell breaks loose. SP Rathika appoints SI Moosa Raaza, a straightforward cop who's infamous for his doggedness, as the Lead Investigator.

When SI Moosa Raaza seeks DNA testing to identify skeletal remains, the results reveal a match to the very victim Mani is imprisoned for murdering.

Haunted by Mani's suicide attempt in prison, SI Moosa Raaza is consumed by doubts about Mani's guilt in the double murder. As testimonies crack and friends reveal secrets, Mani himself refuses to defend his innocence.

SP Rathika brings in her lawyer-husband Sukumaran to help with Mani's case. Mani opens up to SI Moosa and Sukumaran and recalls what happened with him and Nilavathi.

Mani's memories of Nilavathi haunt him as Moosa presses forward despite political pressure. DNA results disappoint. Nilavathi's father confronts Moosa about reopening wounds.

SP Rathika and SI Moosa face the IG's hostility over DNA evidence linking six murders. He wants to wrap up the case ASAP. Media frenzy grows, Mani's mother struggles, and Sumaya fears Raaza's obsession.

Mani reunites briefly with his family. Moosa and Dr. Dhanapal confront baffling DNA contradictions. However, a shocking discovery reveals the source of the "serial killer's DNA".

Moosa's faith shaken by a partly resolved mystery, decides to take a firm hand with Mani and Sundaresan to uncover the hidden facets of Mani's past.
