50 THRILLER PLOT IDEAS (and Other High-Stakes Story Ideas)

This list focuses on thriller plot ideas and crime stories, but many of the ideas could be also used in other genres, such as mystery, fantasy, science fiction, and romantic suspense. I thought of these as writing prompts for adults, but I’ve learned that some teenage writers have used them, too!

I had a lot of fun making this list. Some of the ideas are broad, and some are more specific. I included a few examples from movies and books that can inspire you.
