The four actors gathered in the studio spent three days rehearsing their 30-page script. They were told they would perform onstage on the fourth day. The cast has yet to be decided. Although they are upset about being in a closed environment with their smartphones and watches ripped away, the four devote themselves to rehearsals in order to obtain the roles they want to play. A second-rate actor, an unpopular actor, a bad actor, and an actor who can no longer find satisfaction in acting as directed. Their no-turning-back situations are gradually brought to light during rehearsals, revealing the women’s respective natures. Their performances collide as they give all they’ve got for their acting careers in this space where there are no rules nor even a director or producer. The fourth day arrives. As the masked audience watches, will they be able to show their true natures as actors and deliver a successful stage performance?
