Immediately immersed into the world of K-pop, its culture and their challenge, the band from the UK discover the rigours and potential rewards as they meet their mentors and perform an ‘evaluation’.

Determined to bounce back from an underwhelming first evaluation, the band take on a dance challenge 555 metres in the air and perform live for the first time in front of an audience.

As band member Blaise struggles to find his place in the group, the boys attempt the bedrock of any K-pop band - the music video.

The boys try to build bridges with band member Blaise, who’s feeling increasingly isolated. Will blindfolded choreography be enough to impress the K-pop creator Heejun Yoon?

The band need to improve their stamina and enrol on a military fitness bootcamp. But the K-Pop creator Heejun Yoon has a surprise evaluation which challenges the band like never before.

As their hundred days draw to an end, the band must impress dignitaries at the British embassy and a room of eager K-Pop fans. Will they win Hee Jun Yoon’s approval before heading home?
