A murder on a luxury liner. Everyone looks like a liar.
About
1928, the luxury liner Leviathan is crossing the Atlantic. Caught in a storm, the ship has become a massive locked room on the sea.
The next morning, the passengers gathered in the dance hall are told a shocking truth by the Captain: Lord Arthur, one of the passengers, has been murdered.
Lord Arthur's child, Guest, is inevitably drawn into the incident. An investigation begins, led by Inspector Graves, who happened to be on board, and the private detective Lucien, who also happened to be a passenger.
To hide their own crime, the culprit must erase evidence at the scene, cast suspicion on other passengers, and keep lying until the very end.
Can the detectives catch the killer? Or can the killer deceive the detectives and escape this stormy night?
The curtain rises on a closed-circle mystery.
