Due to an explosion, four teenagers are caught in the tunnel between two subway stations. Suddenly the two girls and two boys have to relate to one another in a whole new way, and to the wounded and dead in the trains. At the same time, they have to try to escape the caved in tunnel. Are they walking towards life or death? They are in a sort of purgatory where all normal laws are invalid, and they are under pressure. They all have their own histories and conflicts, and the drama they are now part of, along with the relationships that emerge, bringing new light to their lives.
