Scott, a young man from Manhattan, finally pops the question to his girlfriend... who promptly says "no."
He's so dejected that he accidentally drops the ring he used to propose into a storm drain.
The ring keeps falling deeper and deeper underground. It falls down into the sewers, then further down into... a movie theater?
Wait, is that a jet plane? Huh? Why are we in the Old West now? What are cowboys doing underground?
Turns out that deep below Manhattan there's an underground dungeon where America's past lives on!
Will Scott be able to traverse it far enough to find his ring?
