When a peaceful young man from the hard streets of gangland Los Angeles accidentally travels through time and witnesses his grandfather commit murder, he fights to change the past without becoming as violent as his neighborhood. Note: Series pilot for an hour-long drama.

There is a lot going on in this story from what you explained. It's a little confusing. Adding time travel to a storyline can be risky, because it has been done so many times. In addition, it has to be clear so everyone gets it. Remember you have to pitch this idea. If you have to take time to explain this to a producer , it's a no go. Look into movies like the Butterfly Effect, Project Almanac, and the Time Travelers Wife for examples. That will help execute your idea better into a simple yet interesting concept.

I hope this helps. Happy writing.

What special twist, unique take does this take on the time traveling trope that hasn't already been explored in other films?

What is at stake for the protagonist?? He may want to stop his grandfather from committing murder.? But in drama that's not good enough.? He needs to stop the murder; he MUST undo the past -- or else.

Well, or else what?? What is the do-or-die, life-or-death reason why he MUST undo the past?
