Abducted for an adventure

I just want to start with this is my first time making something like this and know basically nothing of storytelling but I wanted to throw this pitch out there for people to see since I couldn’t find anything else like it so if anyone can do better please do so look at my idea and make it better You are a regular every day human or just yourself for a long time I had this idea that if I was abducted and treated like a criminal and mistaken for another person so the story begins with you just sitting on a bench in a park when bright lights blind you and knock you out you awaken in a advanced alien holding cell confused and scared until the jailer comes in a very tall four armed bi pedal creature speaking in a mono tone voice in an alien language you can’t understand and are taken to an execution stand in the middle of what must be the city central above you see a balcony with what look like aliens but wearing apparel that suggests they are generals and politicians and right before you get your head cut off one of them speaks out STOP! you look up to see them clearly it’s a human man more importantly you real father who left when you were 6 confused the townspeople look up like what’s going on and your father says my child is innocent and will not be executed that sends shockwaves throughout the city they almost killed a politicians child. The story after that point is yours to play with.
