[2][3] The protagonist (a well dressed man) is standing on the ledge on the seventh story of a tall building, contemplating leaping to his death.
He is interrupted by the colorful residents of the seventh story who are too caught up in their own lives to notice the man or question his being on the ledge of the building.
The man hasn't much dialogue until near the end, when he explains that his daily routine was thrown off when he woke up and lost track of what day it was.
Man is stationed on the ledge and the rest of the cast plays their parts through the various windows.
One of the windows is set to give the impression of a party, whereas another is dark to represent Leonard’s apartment.
