The TV series "Command Z" is a sci-fi comedy about time travelers who try to prevent an impending apocalypse. In 2023, a strange trio of kids suddenly appears in the middle of a metropolis, claiming that humanity will cease to exist in the near future. In order to change this grim future, the heroes must complete a series of seemingly absurd but very important missions: prevent the merger of Amazon and Walmart, disband police unions, and sing a song from an old movie.
