Cassandra Bowden is a flight attendant who wakes up in a Dubai hotel room to find a dead body next to her. Hungover and having no memories of what happened the night before, she doesn't tell anyone about her discovery and departs as usual on her next flight to New York.
Once there, Cassandra is confronted by FBI agents who have questions about her recent International layover. But without the ability to piece together exactly what happened, she starts to wonder if she could be the killer.
Based on Chris Bohjalian's 2018 novel of the same name.
