Crimson Fire has many friends throughout Equestria. However, there's one thing she has never told any of her friends. Crimson has a dark secret: She works in the Rainbow Factory, a factory based on the murder of innocent souls in order to make the rainbows the ponies are familiar with today.

Crimson has never wanted to hurt anypony. But when she begins working at the Factory, she is forced to kill. One day, when Crimson's best friend, a young alicorn named Diamond Water appears in the Rainbow Factory, Crimson decides she has to help her friend escape, even if that means she has to die herself for betraying the Factory.

But helping somepony from the Factory is no easy task. There are guards and surveillance cameras in every hallway and room. There are booby traps everywhere that are placed there specially for prisoners. The chances of not getting caught are slim, and the chances of escaping alive are slimmer.

Will Crimson and Diamond be able to make it out alive? Or will they both die in the Pegasus Device?
