Mundos opuestos(2012)

Mundos opuestos is a Chilean reality competition series that isolates 22 contestants in a house southeast of Santiago to live in two opposing worlds. One group inhabits "the life of the future" while the other lives "the life of the past," separated by a glass wall that lets them observe each other constantly. The two worlds meet only in a shared courtyard called "the present," where direct interaction happens. Each week, both groups compete in physical challenges to determine who advances to which world and which contestant faces elimination. The show tests how participants adapt to radically different lifestyles while competing for survival in the competition.
