If we don't do something to disrupt this auction, Viggo will make so much gold, he'll be able to buy an armada of dragon-hunting ships and reinforce his empire. No dragon will be safe, and eventually, he will set his sights on Berk. And on our dragons.||”|

This section requires expansion.
The episode starts off with Trader Johann eavesdropping on two of the Hunters, one of which has the map of the auction. Trader Johann takes the map as one of the Hunters goes away, and is safely picked up by Hiccup.
The Riders follow Dagur's letter but need a plan to get in the premises of the auction. Snotlout, being the most unfamiliar Dragon Rider to the Hunters, disguises as a blond, arrogant young man with Gobber as his valet. Before putting the plan into action, Hiccup has to convince his father to take along all of Berk's gold, Stoick being reluctant. Johann, playing a significant part in this episode, happens to be hiding the Riders in the storage of his ship, and offers their dragons as a peace offering for safe trading passages. Viggo, suspicious, almost finds the Riders but Toothless, who is hiding with them, covers up. Meanwhile, Snotlout and Gobber are waiting for Ryker in front of Viggo's tent as Snotlout obnoxiously asks for "permission" to enter to count his money. Whereas Gobber finds a dragon he mutually understands and likes, even if Ryker remarks that the dragon is not worth much, despite the fact that it's the only dragon that can eat through dragon-proof metal. Inside the tent, they manage to find the Manifest for the auction and subtlety hand it to Hiccup, who is waiting outside with Toothless. On one hand, the twins and Fishlegs are searching for their dragons. At some point, Dragon Hunters start patrolling the area, making sure that no intruders spoil the auction.
- The title of the episode is most likely a reference to the movie Last Action Hero.
- Coincidentally, F. Murray Abraham starred in this movie.
- This episode explains how Gobber got Grump. Their meeting is similar to how Stoick met Skullcrusher.
- Both Vikings thought their dragons were magnificent when they first saw them and were the first to show the dragons respect or understanding.
- The Riders first learned about Viggo's dragon auction in the previous episode from Dagur's letter.
- The guest Viggo and Ryker were expecting had one of the insignias as Drago's army. He will later be identified as Krogan.
- Krogan makes his debut in this episode.
- Even though Gobber took out his fake tooth, when he said disregarded Hiccup's plan, it was back in his mouth.
- Ryker threatening to make a "delicious meal" out of Grump may be a reference to the books, where the Roman Consul ate lavish meals made of dragon flesh.
- This is the second time a character has dyed their hair. The first was Astrid in "Heather Report, Part 2" when she was pretending to be Heather.
- Trader Johann's comment about ring-tailed lemurs might be a reference to King Julien from the Madagascar franchise, another production created by Dreamworks Animation.
- Windshear does not appear in this episode. This is the first time she doesn't when Heather isn't spying on the Hunters. It is possible that she did not partake in the Riders' mission because the Hunters may recognize her.
- When Ryker suggests eating Grump, the skin around his waist is missing.
- Heather does not appear at the end when all the riders escaped. This is the second time that has happened, the first being "Stryke Out".
- Viggo obtains all of Berk's gold.
