The first half of the movie retells the events of the first two episodes of the TV series with a few additional scenes. Following the events of the second episode, the heroes are soon called in to chase after a thief named Robin Baxter, who has stolen a statue that represents the importance of heroes. The heroes chase after him into an amusement park but find him near-impossible to catch due to his NEXT ability, leading to infighting among the heroes. As Robin heads towards the observation deck, where he could use his power to escape, Barnaby gets the idea that allows him to catch Robin. The next day, Barnaby learns that it was Kotetsu who helped convince the other heroes to let Barnaby go on his own as he trusted him. After the crisis is over, Kotetsu is forced to treat the other heroes to another hangout as repayment for asking them to let Barnaby capture the criminal. (thetvdb.com)
