PI Meena

A young man is killed in a car accident. When the man's mother, Chandana, informs Meenakshi that it was not an accident and asks her to investigate, Meenakshi refuses, claiming that private investigators have no business analysing homicides.

Meenakshi, still sceptical, begins investigating the homicide case. She starts to suspect that the deceased guy was somehow connected to a mysterious viral epidemic in the Eastern Himalayan village of Littnong.

Meenakshi, now convinced that the young guy was murdered, embarks on a perilous trek to Littnong in search of the perpetrator.

Meenakshi begins putting together her idea around the virus. She soon learns that her own life may be in danger.

A virus begins to spread in and around Kolkata and Meenakshi's investigation accelerates; a Central Intelligence officer cautions Meenakshi to avoid something far beyond her comprehension.

The viral outbreak takes over Kolkata; Meenakshi associates the Kolkata virus with the Littnong virus.
