Mistaken

The smooth life of a 19-year-old boy's life was going just fine until it goes into a different direction as a strange girl that is the same age as him, enters the young boy's life. This strange girl claims that he has been seen committing several crimes by a lot of eyewitnesses, but this person claims to know it was an imposter.
An exact look-a-like, and offers a way out of what will undoubtedly be a very tricky situation. Sure of the truth in this situation, but somewhat distrustful of this strange girl, and the young boy hastily agrees to the proposal, it all feels very exciting, as if a big adventure was about to begin.
But what if this strange girl is pulling a prank. Or what if this proposal is wrong or missing important details. How could an ordinary young guy like him end up in a situation like this? Time to find out for the better or for the worse himself. If this boy doesn't find out why he could end up in prison for years for something he doesn't ever even remember doing. It also turns out that the prison site isn't any ordinary site.
