​Would you spend a night in a haunted house? Colonel Mortimer did, and he never came out again!
Is the bell tower suite haunted? Colonel Mortimer doesn't think so, he doesn't believe in ghosts. His club associates dare him to spend a night, so he brashly does.
Sibyl, the mansion's housekeeper, reluctantly makes the Bell Tower suite ready, but fears for his sanity.
Alf and Bert, the security guards, don't believe in ghosts either. Always ready for a prank, they can't resist the temptation to give the Colonel a solid fright.
Nobody expects the outcome...
