Dj Steph is a young radio deejay on the rise, who gained a lot of popularity on social media and every evening hosts a radio show with a large following, during which he receives calls from his fans. One evening, a call chills him to the bone: a cold-blooded stranger announces on live radio that he plans to take his own life, making himself explode in the middle of the city.

Britt Reid (Seth Rogen), the heir to the largest newspaper fortune in Los Angeles, is a spoiled playboy who has been, thus far, happy to lead an aimless life. After his father (Tom Wilkinson) dies, Britt meets Kato (Jay Chou), a resourceful company employee. Realizing that they have the talent and resources to make something of their lives, Britt and Kato join forces as costumed crime-fighters to bring down the city’s most-powerful criminal, Chudnofsky (Christoph Waltz).
