In the beginning, an archaeologist and explorer known as Indiana Borgnine is in search of the fabled Hanging Gardens of Babylon. After reading some lost scriptures, he determines that the only way to see them is to travel to the very top of the 64-story Tower of Babel. Upon reaching the Tower, he discovers that the only way to access the floors above him are to solve some challenging puzzles involving loose L-shaped blocks that he finds throughout the Tower. To his great surprise, the blocks are capable of balancing very well on top of one another, in order to form staircases.
