Parada 88 - O Limite de Alerta (1978)

Residents of the city of Parada 88, contaminated in 1994 due to the explosion of a chemical industry reactor, live in plastic tunnels, the only way of life that can guarantee their survival, since oxygen, which has become a good consumption, used needs to be reused so as not to generate more expenses. One day, Joaquim wins a lottery that gives him enough money to pay for his and his family's oxygen; but to claim the prize, he'll need to go to the ruins of the factory to collect news from a group of contamination experts adventurers posted there.
