This film begins with Acts 8:22 of Acts of the Apostles, 'Repent of this wickedness and pray to the Lord in the hope that he may forgive you for having such a thought in your heart.' It is a story that asks questions to Christians who believe that repentance has been completed with simple prayers. Can our sins disappear so easily just by kneeling and praying desperately, just as a water bottle that has drunk water becomes a clean empty bottle? This work sarcastically takes repentance lightly and asks back the meaning of true repentance.
