Ringolevio (1972)

 * It's a game. A game played on the streets of New York, for as long as anyone can remember. It is called Ringolevio, and the rules are simple. There are two sides, each with the same number of players. There are no time limits, no intermissions, no substitutes and no weapons allowed. There are two jails. There is one objective.
