At Paxy's Village, Dingo and Paxy are having a curry making competition with Netto Hikari, Raika and several villagers serving as the judges. After sampling both contestants' dish, the results are tallied and Paxy won by a landslide, with only Raika voting for Dingo much to his surprised. Netto commented that the possible reason Dingo lost was because of the curry that normally served at MaHa Ichiban uses meat and thus, he was inexperience serving seafood curry. Upon hearing Netto's comments, Dingo order a rematch, this time using meat but Paxy states that they aren't any meat in the village as they have abundant of seafood to feed them and thus, there is no need for them to go inland and hunt for food. Determine to find some meat, Dingo decides to go hunting, with Trill following him.

After walking for some time, using Dingo's tomahawk as guidance, he and Trill found a lone mammoth and started chasing it. Eventually, the mammoth was cornered at the edge of a lake and Dingo attempts to take it down but the beast prove that it would not go down without a fight. Seeing how strong the mammoth is, Dingo sends in TomahawkMan to assist him. Suddenly, missiles are fired from the lake at them by a Navi named DiveMan, the resulting explosion killed the mammoth. Once he lands, DiveMan takes the mammoth's carcass and warn Dingo to stay away from the lake. Angered that their hunt was taken away, TomahawkMan attacks DiveMan but he quickly retreated back into the lake. When TomahawkMan attempts to follow him, DiveMan release several bombs to stop him from chasing. As DiveMan disappear from sight, Dingo noticed that he is heading towards a castle on the other side of the lake.

The castle is owned by DiveMan's operator, Captain Kurohige who ordered DiveMan to open one of the dam's valve. This temporary releases a small flow of water to one of the village downstream. It is revealed that Kurohige and his accomplice Chirol have been hoarding the water in the dam and have been making the villages downstream pay them if they ever wanted any. At the control room, Kurohige is seen contacting Zoano DarkMan, who had survived his previous encounter with Glaga and Falzer, about the recently caught prisoners. Meanwhile, Dingo is determined to get his prized back and made a canoe to get to the castle and manage to get there by nighttime without getting detected.

Inside the castle, Dingo and Trill encounter several viruses but manage to avoid detection. They ended up at a prison and found several prisoners inside who were caught trying to open the dam. Dingo promised to free them but was found by viruses guarding the prison and quickly run away. At a balcony, Trill ask Dingo to get him to the tower on the other side of the castle as he felt something there. Using a rope tied to Dingo's tomahawk, the two manage to get to the tower. Trill crawls into a space hole on the roof and enters a room where Iris was imprisoned. It was revealed that without the Synchronizer, Zoano DarkMan had no used of her and imprisoned her in the castle until Trill is found. Once Dingo managed to make a larger hole to the roof, he attempts to pull both Iris and Trill out. However, he was already detected and Chirol sends her Navi, CircusMan to attack him. In response, Dingo sends TomahawkMan to buy him sometime while he saves Iris and Trill.

Meanwhile, Netto and Raika have been trying to find Dingo and Trill ever since they left the village. After following their footsteps to the lake, the two of them heard the battle between TomahawkMan and CircusMan at the castle and proceeds to head there. From his telescope, Kurohige noticed the two of them and sends DiveMan to stop them. While Raika and SearchMan battle the submarine-like Navi, Netto proceeds to the castle and sends in Rockman to fight several viruses. After getting rid of them, a bright light shines above them, signalling the arrival of a new threat, Zoano DarkMan. Rockman attempts to fight him but as before, Zoano DarkMan shows that he powerful opponent for him to fight alone.

Upon getting free, Iris noticed that the heroes requires some assistance and tells Trill to unite with Rockman. Although Trill reminds her that if he does so, Rockman will turned into a beast and go on a rampage again, but Iris comforts him as she can control him while in Beyondard. Using her powers, Iris fused Rockman and Trill, transforming Rockman into Beast Out Falzer. For the first time, Rockman is in control of his Beast Form and didn't go on a rampage. Seeing how strong his opponent has become, Zoano DarkMan also enters his Beast Form. Even so, he was no matched with Rockman's new powers and was deleted easily. With Zoano DarkMan defeated, Kurohige and Chirol had no choice but to retreat by entering DiveMan. However, he was swept away by the current that Zoano DarkMan caused after crashing into the dam. With their enemies gone, Iris turn Rockman back to normal, seperating him and Trill.

Somewhere downstream, Meiru and Enzan are having dinner by a fire pit and noticed the previously dry river behind them is now flowing. Realizing something must be going on upstream, the two decides to investigate. With Kurohige and Chirol gone, the dam is unlocked and all the rivers are flowing again, giving life back to all the villages downstream. Dingo (with a huge piece of meat tied to his back), Trill and Iris return to Netto and Raika and watched as the villagers celebrate. When Netto asked Iris how is she able to control Rockman's powers, Iris tells him to follow her to the Dimensional Area Laboratory where Trill was born and she'll explained everything there.
