Spying the development going on at the castle of Phobos Caleb and Aldran finds out why they drill. They, in fact, are looking for tunnels from the Meridian’s planes towards the castle. Except there is none, however the threat just growth bigger. If they dig deep enough they are able to reach the infinite city, the hideout of the rebels. At that moment Blunk rushes towards them, holding a backpack of weapons and armor. In his way to Caleb he stumbles and announce everyone their currence.

Alerted the guardians alarms the alarm and defend their drill as the rebels approaches. Caleb manages to get on top of the drill, but he’s busted down into the waters. While he’s swimming in the giant pool to get up, Cedric blows an horn which makes everyone obedient towards the blower. Caleb reaches the surface and flees as he notices he have to fight the rebels and the gaurds all together.

Meridian’s life is in contrast with Heatherfield. Will sneeks towards the garage of Matt, inside they practise playing music. Suddenly the garage door opens, but Will’s not looking. The three guys sees a wild dancing Will in front of them. Surprised Matt calls her name, she turns around and blushes. She inmediately thinks up a line and goes away with it. However, Matt asked her out… it’s a date!

Together with her friends at Hay Lin’s family restaurant she announces her triumph. Totally in heaven Caleb spoils her day. With sweet on his forehead Caleb informs them about the recent events. Yan Lin shocks as she knows about the transmarchers, though she has no clue how to solve.

So she redirects Caleb to the ancient one. Caleb turns around and steps outside to get Blunk and moves towards the ancient. Dissapointed about Caleb uninterested glance at his shiny new horn he goes with him. Inside the restaurant Will steps up, it’s up to them to take the drill down.

Shaking the earth Cornelia, warns the transmarchers about their currence. It’s not the purpose of the guardians to hurt them while they demolish the drill. Still they just won’t respond until Cedric calls the attack command. They manage to get Taranee on her back while she’s underneath the spike of the drill. Frigthend she calls for help which is given by Hay Lin. She takes the a transmarcher and the gaurdians assembles. Will appraoches the female transmarcher, she’s not responding. Suddenly she screams to betray the gaurdians attendance. They need to leave her behind since they have no clue how to undo this powers.

Blunk and Caleb kneels down to the ancient. She tells them the horn of hypnose is able to create transmarchers. The owner will be able to command the transmarchers once they heared it’s tune. However a tune exists which can undo these powers. Caleb listens to the tune as Blunk suddenly realise he found the horn and taps Caleb. First he’s not willing to listen to Blunk, until the ancient displays the horn of hypnose using the reflection of the water.

Like fate is toying with them Hay Lin found the horn at the garbage container. She smiles, finally some luck, the horn will be the best excuse why she’s late helping out in the restaurant. She practised blowing the horn at school, because she joining the school band. Happy with her excuse she takes the horn with her. The door rings and Hay Lin opens the door where she meets mrs. Knickerbocker.

Her father is acting odd, he literally does with Hay Lin says. Mrs. Knickerbocker leers down to Hay Lin who grins, informing her, her father has a lot of stress lately. But, he’s able to go on without her, she has to go. She quickly hands over the horn and says it’s for the school band and slams the door down.

At school the girls talks, Tarnanee almost have a date with Nigel. Cornelia smiles but suddenly is bumped by a school bands player. Backed off the girls watch how the school band marches away from school, to the city. Alarmed the girls know, the cause is in the neighbourhood.

Quickly they search for Caleb which they find in real trouble at the scrap yard. Surrounded by the transmarchers rebels Caleb is paralised. He will never attack his own people. Lucky the gaurdians are able to hold up Cedric and flees with Caleb.

Away from battle Caleb tells them about the tune, melody and the horn. Hay Lin face breaks down, the school band… Martin was blowing the horn she gave, which means if they are marching through the city he have made a lot of transmarchers by now.

Warned the gaurdians searches the transmarcher but it’s too late. Cedric already took the horn of Martin and uses the horn at Hay Lin. Hypnotised she attacks the gaurdians who has no choiche to withdraw Kandrakhars powers.

Near the moment of defeat an heavy string of snairs blows through the sky. At the top of the roof a guitar player pulls the strings. As Caleb plays the melody the horn crumbles to dust and the powers becomes nullified. Everyone wakes up, like they have sleeped the whole trip. The students goes to the school’s party along with the girls, excpept for Will who needs the close the portal first. Late Matt worries about Will’s arrival. However he worries for nothing, no moment later he finds Will in front of the stage. He pulls her up the stage and together the sing, dance and play.
