A damp, cold warehouse on the edge of the harbor. Outside, guard dogs bark menacingly; inside, a pale light flickers from a locked cubicle. Here, hidden from the world, is said to live "Mr. Ariel"—a legendary billionaire and patriarch of a gigantic empire.

The ambitious, coldly calculating top manager Mrs. Glassy desperately needs his signature for a crucial deal. But standing between her and the coveted success is Row, the cynical, unpredictable, and armed guard of the warehouse. What was planned as a lightning business visit quickly escalates in the cold, gloomy hall into a merciless psychological power struggle.

Who really has control in this duel?

And what dark secret lies hidden behind the door of the shed?
