“It’s Jaws in Space” (for Alien) is a classic.

With so little time, you can’t get hung up on plot. Focus on what makes your protagonist(s) tick, what external and (more importantly) internal challenges they are going to overcome, why we are rooting for them and how they are going to change by the end of the story.

Vivid characters, strong personal relationship to story/ world, key visuals but nothing too flashy. No plotline, simple language. Good luck 🤞🏼
