20 Plot Ideas to Jumpstart Your Next Novel

Every writer knows the sensation of the "blank page problem." You sit down, ready to work, but the cursor just blinks at you. It isn't a lack of talent; often, it’s simply a lack of a starting point.
Plot ideas are best viewed as seeds. They aren't finished blueprints but rather sparks intended to ignite your own creativity. A prompt written for a thriller might work just as well in a romance setting if you tweak the stakes. The goal is to mix, modify, and make these concepts your own.
If you are looking for guidance on what to do after you have the idea, our resources page covers many aspects of the drafting and revision process. But for now, let's focus on getting that first concept on paper. Here are 20 plot ideas organized by genre to help you find your next story.
Mystery and Thriller Plot Ideas
Mystery and thriller readers come for the puzzle and stay for the tension. These prompts focus on distorted perceptions and the unsettling realization that things are not as they appear.
1. The Unreliable Witness
A detective’s key witness in a high-profile case keeps changing their story. The detective initially suspects the witness is lying, but closer inspection reveals something more sinister: the witness’s memories are being systematically altered. Someone with access to experimental technology is rewriting the witness's mind in real-time. The detective must solve the case before the witness’s original memory, and their identity, is erased completely.
2. The Anonymous Confession
A small-town journalist begins receiving anonymous voice messages confessing to a decades-old crime that officially ended in an accident. Each message reveals a new, verifiable detail that was never made public. As the journalist digs deeper, they discover the confessions are being sent from different locations, and at times when the supposed confessor couldn’t possibly be recording them. The truth emerges slowly: the messages aren’t coming from the killer, but from someone who knows the crime was covered up and is using the journalist to expose it, before the people who buried the truth realize they’re being hunted.
3. The Wrong Body
A burnt-out medical examiner is performing a routine autopsy when they realize the body on the table isn't who the identification says it is. The real person is alive, currently in witness protection, and the body on the table was a decoy meant to flush them out. Now that the examiner knows the truth, they become the next target.
4. The Inheritance Clause
Five strangers are invited to a remote estate in the Scottish Highlands. They discover they are all named in a reclusive billionaire's will, but there is a catch. To claim their share, they must spend 30 days together in the house without leaving. Tensions rise as they realize they were chosen not for their virtues, but for their darkest secrets. Then, one of them dies, and the survivors realize the "inheritance" is actually a elimination game.

As these premonitions start coming true, the dealer realizes they are holding the roadmap to a catastrophe, and the people who manufactured these memories want them back.
6. The Last Human Job
Artificial Intelligence has replaced every human job except one: the "Ethical Decision Maker." Machines can calculate efficiency, but the law requires a human to sign off on moral dilemmas.

The crew has been left in the dark to preserve the "social experiment" of the generation ship.
8. The Consciousness Upload
A tech billionaire uploads their consciousness to the cloud to achieve immortality. Upon waking in the digital afterlife, they expect paradise. Instead, they find themselves in a war zone.

10. The Magical Plague
A strange disease sweeps through the land. Instead of killing its victims, it grants them wild, uncontrollable magical abilities.

11. The Forgotten God
In a world where gods draw strength from worship, your protagonist discovers they are the sole remaining believer of a forgotten deity. Because the god has only one source of power, the dynamic shifts; the mortal can make demands of the god. But after centuries of neglect, the god’s memory is fragmented, and their attempts to help often lead to chaotic results.
12. The Library Between Worlds
A quiet librarian discovers a hidden door in their archives leading to a section that shouldn't exist.

And by gathering together, they have inadvertently summoned it back.
20. The House That Renovates Itself
A young couple buys a cheap fixer-upper. They start renovations, but every morning, they find their work undone. The wallpaper is back up; the wall they knocked down is standing. The house isn't just resisting change; it's slowly changing itself into a layout that matches the childhood home of one of the owners, forcing them to confront a trauma they thought they had left behind.
How to Develop Your Plot Idea
Once you have chosen a prompt, the real work begins. A premise is just the starting line. To turn it into a narrative, you need to interrogate the idea.
Ask yourself, "What is the worst thing that could happen to this specific character?" If you have a protagonist who values honesty, put them in a plot that requires deception, like The Anonymous Confession. If your character craves control, put them in The Magical Plague.
Don't worry about getting the structure perfect in your head. Writing is an iterative process. You might start with a mystery and find it evolving into a character study. That is a natural part of discovery.
If you reach a point where you have a draft or a detailed outline but aren't sure if the pacing works, technology can offer a fresh perspective. Tools like Inkshift can analyze your manuscript to provide detailed feedback on plot structure and pacing, acting as an objective critique partner before you send your work to a human editor.
Conclusion
Plot ideas are everywhere. They are in the snippets of conversation you overhear at a cafe, the news headlines you scroll past, and the "what if" questions that keep you up at night. The best plot for you is the one that you are excited to return to day after day.
Don't wait for the perfect idea. Pick one that intrigues you, start writing, and trust that your unique voice will make the story yours.
