The film unravels adventures of various attempts by individuals and groups during their search for gaps in the Wall in order to permeate and sneak past it. Lookouts, fear, angst, running, permeation, jumping off, crawling, passing through dark passages, are stages of a complex process of passing through to the "other side" and require a very specific state of mind. Some attempts end in failure, and others in success. Some are caught by the Israeli soldiers and others reach their destination. It's a cat and mouse game, in which failure leads to more persistence and success is an antithesis to cat's theories of security.
