Years of poor maintenance and filthy work conditions, the Sodor ironworks begins to leak a poisonous liquid. The rest is chaos.

The Steam Team seems to be having a normal life. Nothing looked out of the ordinary. Everyone seems happy. But, that isn't the case, at least not for one member. Meet Thomas the tank engine, the founder of the Steam Team. There's a secret about him that only his brother Timothy knows. But, he was starting to need more support and had to find someone to help. And his friends are the only ones he would ever trust with a secret as deep as this one. But, he doesn't know if they'd be okay with him, so he doesn't get help until he's at him breaking point.
