An average-everyday guy with a crappy life wins the $42 million lottery. But what he doesn't know is that the system is corrupt and they now want him dead.

You say a corrupt system wants him dead; however a system is faceless, you need a main antagonist to put a face on that corrupt system.

Alright mine still needs work but I hope you see what I did. I started with the event that triggers the story then added an antagonist.
Hope that helped, good luck with this!
