The past few months you’ve been in prison and your sentence will keep you there for the next decade. You spend most of your day together with a small group of inmates. They protected you on your first day and you feel you can trust them. They’ve got your back and you tell them you’ve got theirs (for what that’s worth).

One afternoon you strike up a conversation with a fellow inmate and he tells you that a great mathematician, Walter Castle, used to live in your cell. He was transferred to another prison a while ago. Walter Castle was somewhat of a legend amongst the inmates. The prison director and guards were afraid of him. Not because he was big or strong, but because they were afraid that he would escape. A prison break would damage their reputation. They made up some lie that Walter got into a fight and beat up another inmate. Walter couldn’t beat up a fly but nonetheless they transferred him to a maximum-security prison across the country.

You’re not surprised to hear a mathematician used to live in your cell, as it explains all the numbers and weird puzzles on your wall.

The thought of freedom makes you very intrigued about all this strangeness in your cell. You wonder if it all belongs to some greater plan to escape from this hell you call home.

The few months you’ve spent in prison already seem like years and given the choice, you’d choose a life on the run over a life in prison any day. You convince yourself that escaping would be justice. You have been sentenced to ten years in prison for a crime you didn’t commit. Ten years of your life with no hope of a future, for being in the wrong place at the wrong time. It hardly seems fair.

That evening, during lockdown, you tell your friends about what you’ve heard. You and your buddies turn the cell upside down and find closed envelopes hidden in the toilet. This information might just be the start of your prison break. The guards will reach your cell during rounds in one hour, could this be the opportunity of a lifetime?
