Do you know this film/short film -I challenge you?

Question

I'm sure it was by Hitchcock,
It was on tv in the UK around 15 years ago,
A woman was locked up in prison and hatched a plan with an undertaker that she would pretend to be dead, he would bury her and then he'd come and dig her up.
It ended with her lighting a match inside to find him in the coffin next to her,
It ended with her screaming
This has bugged me for years,
Do you know what it is ???
