The key to writing engaging plots is the key to writing all genre stories:

Write characters who want things, and then make them work for those things against increasing pressure.

As long as you have a character trying to accomplish a goal that’s difficult for them to reach, and you make them face harder challenges and grow more as a person the closer they come to reaching that goal, you can make any idea interesting. 

Here are some other things that might help you:

How does pacing work?
Creating strong plots with strong plot points.
What is suspense really?
Combining ideas to create wild and cool stories.
For a word on doubting your ideas, see point #2 here.
