I think it was Stephen King (in Danse Macabre) who said there are only a few basic plots (paraphrasing here):
1) Boy loses girl; boy gets girl back (or any variation)
2) Boy loses girl; boy finds new girl (or any variation)
3) Revenge
4) Quest for something
5) Solving a mystery
The originality is going to be in your voice, characters and plot-devices. It's like playing a guitar. There are no new notes. Everything that can be played anywhere along the neck can be played in the first five frets (it's the octaves that differ).
