Cosentino, the Grand Illusionist, is in danger! He is trapped in a glass ball hanging over the ocean, where dangerous beasts lurk. He will have to undo shackles, a straightjacket, and padlocks to escape! The audience watching him from the pier is terrified, but not as much as when the evil two-headed King arrives on a mission to find his lost sunken treasure. Cos must stop the King from taking the treasure, but first he must avoid arrest AND escape from the glass ball... while underwater! But how long can he hold his breath? Can Cos pull off his greatest illusion ever?
