Blunk finds the Horn of Hypnos, but it gets stolen by Jeek. Irma Lair then leaves for Meridian, along with Matt Olsen and Blunk. The three track Jeek's hiding spot, only to find out that the Knights of Vengeance got a hold of it.
To make matters worse, Will Vandom, Taranee Cook, Cornelia Hale, Hay Lin and Matt Olsen are turned into trance marchers. It is now up to Irma and Blunk to save her friends. When Will Vandom blows the horn at Irma and Blunk, they use earplugs to fake their hypnotism to get close enough to the horn and destroy it.
In the B-story, Irma is mad at Blunk for covering her garage in garbage and is forced by her father to clean it up.
- Although the Horn of Hypnos was destroyed by Caleb in "Walk This Way", it appears for the second time in this episode.
- Irma's transformation into a Guardian was slightly different than it usually appears because of her being a trance marcher.
- This is Hay Lin's second time being a trance marcher, the first time was in "Walk This Way".
- This is the only episode of Season 2 where Nerissa Crossnic does not appear.
- Caleb does not appear in this episode.
- This is the first appearance of Jeek since the episode "The Underwater Mines".
- Blunk remembers that a particular melody will render the horn useless. Two of the tunes he hums are identified by Irma as "Twinkle Twinkle Little Star" and the "Alphabet song". However, both of these songs actually use the same melody.
