As anyone who’s taken part in a theatrical production will know, the real drama is often what’s happening offstage.

Tetsuro Tada (Koshi Mizukami) is a programmer with little prior acting experience who lands a key role in the latest production by Kaerude Kato (Kuranosuke Sasaki), a celebrated director with a well-earned reputation for bullying and sleazy behavior.
