A prisoner (Edd Byrnes) convinces a fellow inmate to smuggle him out of a maximum security prison in another man's coffin.
#318 - S2E18 - February 21, 1964
It wasn't too hard to guess the ending. The acting was quite good though.
I know Edd Byrnes from his role as carhop "Kookie" from 77 Sunset Strip.
This episode fairly obviously inspired the film Buried (2010), which was filmed entirely inside a coffin.
there doesn't seem to be anything here
