In the finale of the first season of La Brelia, a mysterious giant sinkhole appeared in Los Angeles, causing a family to be separated. A portion of the mother and son were trapped in the sinkhole, while the father and daughter were outside. They had to work hard to survive and solve the mystery of where they were and whether there was a way home. In addition, an Air Force pilot was recruited to lead the rescue mission. However, the specific ending was not mentioned in the search results provided.
It's hard to say for sure. 'Tar' could be a completely fictional creation or it might draw inspiration from real-life situations and then be embellished.
