When Merlin is asked why Bog Lake is boiling, he learns that the key Lance can use to free Sir Lancelot is within. Tone creates a portable shed with scuba equipment of vines so Artur and Lance can search for it. The three, Wally, Brick, Breeze, and Lug avoid the Warlords on their way out thanks to a Merlin's decoy, but Morgana learns of the key about the same time the Warlords realize the trick. The Warlords attack just after an underwater chasm opens and the key falls in, and cut Lance's scuba so he topples in as well. The knights believe he has died, but Morgana realize he's alive in an underground cave. But she and Viper, determined to claim the Key of Truth, don't intend to let him stay that way...

Merlin dreams that Viper possesses a Key of Truth and defeats Darren, and concludes that Darren's key is in Morgana's and the Warlords' domain. Tone builds a hang-glider for Arthur, Lance, Darren, and Trunk to invade Castle Morgana, but Darren falls into the castle grounds and is captured. Morgana intends to use a machine to unleash a potion which will turn him into a Warlord himself, then, learning how many others must still be nearby looking for him, do the same to them. The other knights are fighting more than time through her danger-infested castle to reach him and the key first.

Tone and Merlin share a dream that, during a battle, Tone falls through a tree and finds himself in a hospital where he sees his mother in a coma which it's believed his presence could help her recover from. Merlin realizes it was a true vision since he had another of the same tree, the new location of the Key of Truth for King Arthur - which can actually be used along with another to transport the knights home, if briefly. But the tree is inhabited by the giant Grinlap. Arthur, Tone, and Darren with his own key set out to retrieve it so Tone can see his mother awaken, but the Warlords don't intend to let them have another key...

During a battle too early to tell which side is winning, the Warlords abruptly retreat when a lunar eclipse begins. Merlin remembers too late that it has transported the three attained Keys of Truth through an unspecified time in the twentieth century, which Morgana has told the Warlords. The portal is Grinlap's tree, so Arthur, Darren, and Tone return to time-travel again and reclaim the keys, but the Warlords are ahead of them. Annoyed by their confrontation in his home, Grinlap watches the Warlords go through the portal then throws the knights in. They end up in the 1950s, when an amusement park with a Camelot theme is in the area. While the Warlords cause havoc some are aware of and some aren't, the knights try to avoid attack by them and track down the keys.

Having repelled the Warlords once, the Knights of Justice continue to make their way with Merlin's help toward where Morgana holds Guinevere. Morgana is aware that King Arthur and his knights are still imprisoned so those approaching are strangers. She succeeds in capturing Lance and Trunk, causing Arthur to travel to her castle to rescue them as well.
