The heroes of 'Tiger & Bunny' are back in an all-new feature-length film! Picking up after the events of the Maverick incident, Kotetsu T. Kaburagi, a.k.k Wild Tiger, and Barnaby Brooks Jr. resume their careers as heroes fighting crime in Hero TV's Second League. Their partnership comes to a sudden end when Apollon Media's new owner Mark Schneider fires Kotetsu and moves Barnaby back into the First League, pairing him up with Golden Ryan, a new hero with awesome powers and a huge ego to match. When the heroes are sent to investigate a string of strange incidents tied closely to the city's Goddess Legend, they discover three super powered NEXTs plotting to bring terror and destruction to Stern Bild. With the lives of millions hanging in the balance, Barnaby and Goden Ryan must overcome their differences to contain the approaching doom, while a jobless Kotetsu's resolve as a hero is put to the test as he struggles to help his fellow heroes from the sidelines.

Set on an alternative Earth, Superheroes are celebrities and a high rating TV show rates their achievements, awarding them points until an annual King of Heroes is crowned. Old-school hero Wild Tiger is assigned a new partner with very different views on the heroes role in society but soon a vigilante criminal presents them with a serious problem.
