While at Alex’s memorial, Cassie learns through eavesdropping that there is a flight that Alex was supposedly on that might tarnish his name. She learns its through a company another fellow flight attendant, Nate, works for.

Using his romantic interest in her, she gets a spot on the flight that is leaving from Teterboro airport, an airport for private flights in New Jersey, to Maine. She discovers something very strange when she gets on the flight. Teterboro Airport is no stranger to real controversy — it is where Jeffrey Epstein was arrested.
