Yonatan is filming others and asking them: "If you met a talking goldfish that grants you three wishes, what would you wish for?" He wants to edit a bunch of the responses and make it a film.
Later on we see a man named Sergei who hates being interrupted. Yoni knocks on the door and ask if he can record him, Sergei says no, but Yoni keeps insisting. He finds a goldfish in Sergei's house and goes to it.
Yoni approached the fish very enthusiastically and that startled Sergei. Sergei kills Yoni by accident and the goldfish speaks and tells him that he could use his last wish. He wants to save it for something else.
