In a tense prison interrogation room, FBI Agent Sarah enlists the reknowned Vegas Ghost, Leo, to take part in a high-risk mission targeting the Leviathan casino cruise ship. Leo quickly reads the unspoken grief weighing on Sarah: a fellow agent she relied on disappeared, felled by treachery. Using nothing more than a playing card, he demonstrates extraordinary mastery, breaking free from confinement to demonstrate why he is indispensable to the operation. Leo reveals his true driving force: the vessel harbors clues about his sister Lily’s history, and he turned himself in on purpose to dig up the truth. Before he leaves, he cautions Sarah about the shadowy Abyss crime syndicate and its mysterious mastermind, the Professor. A shaky partnership is forged, kicking off a deadly contest of wits and moral grit. Will Leo’s quest for justice unearth secrets buried for years, or will the Leviathan’s web of lies drag them both down? Trust lies in ruins, resolve is rekindled, and every choice they make must be flawless.
