Balance (1989)

The setting is on a floating platform where a group of evenly and carefully placed men live. Each man is aware that the platform is not stable and in order not to fall to their deaths, they maintain a careful balance of weight to prevent the platform from tipping too far and cause them all to fall. This reasonably harmonious understanding is lost when one man pulls up a heavy trunk. In the ensuing struggle, balance is lost in more than one sense.
