The scientist named Koshkin has found a way to make himself invisible. Is that great? Perhaps it is. It's just that he’s made everyone in this world invisible too. And now he is doing the same to Peter’s world. Agent Omega, also invisible, sets to find Koshkin. So now it’s one invisible person chasing another. As a result, Peter’s Mom, Dad, and Grandpa become invisible as well. Peter simply must persuade Koshkin to give up his visibility formula to help his family—and everyone else too.
