Saw a quick Imdb review but you should avoid that. They do establish a few things. I have my theories. There will be explanations online. An independent show. A giant sinkhole opens up in the middle of Los Angeles. There is a family who are the protagonists. Eve is the mother. A milf. Might be significant that she is called Eve. She has a son and daughter. The ex husband has been having visions. It kind of alludes to who might be a love interest. People and objects fell into the hole only to be transported to another place. A stoner guy named Scott, a psychiatrist, a cop, a doctor and his daughter are amongst the characters introduced. This government agency is investigating. Special effects will be as good as they can be. Apocalyptic. There are unknown threats waiting. Interesting filming locations.
