Shinichi, Ran, and Kogoro attend a trial at which Eri is a witness for the defendant Reika Saito's alibi. Things get out of hand though when Reika begins insulting Eri and Eri threatens to kill her, pointing at Reika with her hand in the shape of a gun. Much to everyone's surprise, a gunshot is heard when Eri says "bang" and Reika drops to the floor dead. Can Shinichi prove Eri's innocence?
