Here's a brief synopsis:
"Let's Get Invisible!" tells the story of two best friends, Max and his neighbor, Tony. They stumble upon an old, abandoned carnival in the woods. Inside, they find a mysterious machine that promises to make them invisible.
Of course, things don't go as planned. They accidentally become invisible, and soon realize that being invisible is not as fun as they thought. They encounter scary situations and have to find a way to reverse the invisibility before it's too late.
