150 passengers boarded Flight 257.
They landed safely.
Three weeks later, one of them is found dead.
Then another.
And another.
Each victim dies in the exact same way, leaving behind no evidence, no witnesses, and no explanation. As the death toll rises, panic spreads across countries, and the police struggle to find the one connection everyone has overlooked.
What began as a routine international flight soon turns into the deadliest mystery the world has ever seen.
With every passenger living in fear, time is running out. Trust becomes dangerous, every clue raises more questions than answers, and the truth hides in the one place no one thinks to look.
Some journeys don't end when the plane lands.
