Eliza and Leo had to travel from the future back in time with alot of other "chosen" sims og give sims all around the world a second chance becuase the world was dying. Something went wrong and they ended up en the prehistoric era without knowing where the other were. Not knowing eachother or this world they now have to get by with the little they have and make sure simsmanity survives allthrough the ages. #HistoryChallenge
