Mithra was admitted to the critical care unit after being acutely poisoned with an unknown chemical. Suspecting it as a murder attempt and in the process of finding the truth, the assistant commissioner of police Krish has come up with many unexpected twists. Rather than an individual's case, it became a national outbreak. Neither the supportive therapies nor the available antidotes are resolving tissue hypoxia. The rapid suffocation is taking up many lives. The challenges are huge. How far the medical team can protect the victims dying from the unknown chemical? What could be the motive for the deadliest outbreak and who is behind such actions? Could the crime investigators able to find the guilty and save the country?

The horror has begun, and from now on, every second is accountable. It is all about life or death in a fraction of a second.
