Deadly Course: A Battle of Human Nature

"Warning! You've been selected and forced to take part in a real-life elimination game called 'The Abyss.'"

"The cruise ship is the board, the passengers are the pieces, and murder is just the opening signal. One unarmed criminal profiler (me), one lone special forces soldier with formidable combat skills (him). One uses intelligence to break the deadlock, the other uses force to clear the way. We go from distrust to entrusting each other with our lives, joining forces against a mysterious organization that wants to use extreme trials to select a 'new humanity.' This isn't just a fight for survival. It's a battle of wits between mortals and 'gods'! Two male leads join forces to tear through the conspiracy in a desperate situation. Dare to enter the game?"
