Scientists investigate a huge meteor that crashes into the ocean off Mexico, and encounter a skyscraper-tall, mobile machine which is designed to syphon energy from earth, including any energy directed at it in an effort to destroy it.
Unfortunately the movie Kronos is not yet available on HBO Max.
