Personally, I always have trouble with plots, so, here are some suggestions:
I was first introduced to the "36 Plots" in a now out-of-print Writer's Digest book titled Theme and Strategy by Ronald B. Tobias. They were created, or defined, by a Frenchman over 100 years ago, but they remain true for fiction today.
Polti's 36 Dramatic Situations
Polti's book is still in print, and translated to English. It's called The Thirty-Six Dramatic Situations
Another good book about building plots, also by Writer's Digest is 20 Master Plots (And How to Build Them)
