Psychic director Natsume and his assistant Momoka decide to infiltrate a yoga club after receiving a strange video. It showed a religious group that worshiped crocodiles called "Owa Jin", which Momoka's younger sister had joined a few years ago. What awaits the two who sneak in with the help of a shark?

Love Shark is a wildly unhinged parody of Japanese paranormal TV and YouTube popularity culture. Natsume and Momoka run the failing psychic investigations channel Big Summer until a clickbait dating show they put on leads Momoka to find true love- with a contestant who is also a man-shark. Cue assassins, magic priests, decapitations, and chaos galore in this hysterical rom-com monster movie.
