i guess by the time i saw this episode and i have see enough twilight zone to have it figure out ahead of time . there be this odd assemblage of character who find themselves at the bottom of a cylinder . they be fine until an overzealous soldier show up in their midst . it be his prime directive to escape and so he garner the force and put them to work to reach the top of the cylinder . there be much discussion about purpose and reason and speculation on their past and but no one can remember anything . they represent different job represent a piper and a ballerina and a clown and a man in a tattered hat . why be they there . it lead to an adventure and be resolve at the end and but i guess i have a pretty good idea before it all happen .
