An architect (Yamada) and his apprentice (Shimizu) are both passionate fans of pro-wrestling.
When there is no work to do at Yamada Architecture, they spend their time wrestling.
Then, one day, an editor (Hanamaki) appears.
The two of them prepare for their first job in a long time, but the man makes a completely unexpected request.
“Could you help me think about a lockedroom mystery?”
