Cover art for Planning A Prison Break lyrics by Receiving End Of Sirens, The

I think Jagfire is close. I wouldn't have thought of the alcohol aspect. My first thoughts were that it was a song about suicide - jail break >> last night in my body. In light of what Jagfire suggests: The prison is the body, in which the mind is master (warden).

Warden's calling for a lockdown: Separate yourself from the outside world

Call on interim inequities: Dwell on things that are not right in your life

Last night in my body; assist in the escape: Thinking of suicide, drink to numb yourself to the act

Then, of course, the alcohol.

The rest I'm not sure of. I think that walking outside, arm in arm so that all we've done is not in vain: means that you were not able to commit to the act - Somehow for now this skin will have to do. This is the last night in my body.

You're still contemplating the act.
