Grime Kids

School's out. Dane, Junior, Bishop, and Bayo want to make the most of their summer. When they bump into Dane's old friend Kai, he has an idea about how. Despite being underaged and it being sold out, he convinces the others that they must attend Rinse's FM's Knights of the Realm, the rave of the summer. Dane and Kai sneak into Rinse FM's headquarters to get tickets, but when police crash the illegal broadcast, their plans are seemingly scuppered. But Kai's persistence gets them through the doors. At Knights of the Realm, the flowing champagne, heavy basslines, DJs enchanting the crowd, MCs going full throttle on the mics and the girls - one girl in particular for Dane (and Kai) - leave each of the boys awestruck. Dane makes the daring proposition that every night should be like this night. They should start their own crew.

The newly dubbed 'Gladiator Crew' plan their roadmap to success. A chance encounter with Rinse FM DJs Slimzee and Geeneus provides an opportunity for Dane to negotiate on behalf of the Gladiators. Dane's crush on Genevieve evolves. After much convincing from Bayo, Bishop uses rudimentary music making software to make his own beats and produce an original track that elicits appreciative head nods and gun finger salutes. Kai bumps into Wiley and DJ Target, both instant legends in this emerging scene, but fails spectacularly in trying to impress them. Overcome with embarrassment, Kai steals a chance to salvage his ego, but at what cost? Kai and Dane's old school tensions bubble over. Lines are crossed, harsh words are said that can't be unsaid, and the future of their friendship is left uncertain.

The boys support Junior at his late mother's memorial. They decide to enter Mic of the Manor, an open mic competition, where crews compete in front of a live crowd for a cash prize and a paid studio session. Genevieve and Dane's connection blossoms. Dane's nan displays signs that cause Dane to worry about her health. With no records for the competition, they turn to a reluctant Bishop. Despite not being ready to share his music with the world, Bishop agrees to come to their rescue. Bayo and Bishop rush to a pressing plant and watch in awe as their first ever record is made. After a rocky start at Mic of the Manor, the Gladiator Crew make their mark and send the crowd into a frenzy. But a surprise judge threatens to reveal that Kai's lyrics are stolen. Kai makes a quick exit, leaving Junior and Dane to discover his secret. Dane convinces Junior to keep it to himself and not to burst Bayo and Bishop's bubble by telling them what Kai did. Donnie presents Bishop with a tempting offer.

After finding out about Kai's misdeed, Bayo goes to visit him at home and urges him to stay part of the crew. Junior's emerging talent as a manager is demonstrated when, in an attempt to restore their reputation, he books the Gladiator Crew their first gig - a house party for Tanika, a girl who saw them at Mic of the Manor. Bishop regrets agreeing to be involved with Donnie's 'work'. He nervously makes plans with Donnie to return Donnie's 'product'. The Gladiator Crew's performance at the party is well received. The night is a success... until chaos breaks out, forcing the Gladiator Crew to escape abruptly. In the fracas, Bishop leaves Donnie's 'product' behind. Stuck between whether to return to the danger at the party to retrieve it or confess the mistake to Donnie - who Bishop begins to realise is an equally dangerous threat - the boys weigh up their terrible options. Dane discovers an issue with Genevieve.

Bishop and Donnie have a tense face to face. Bishop has no choice but to work for Donnie, to pay off his debt. To his surprise and devastation, Dane learns of Genevieve's health condition. On top of it all, the extent of Dane's nan's decline is revealed. Junior and his dad have a long overdue heart to heart about their shared grief over the death of Junior's mother a year earlier. Junior also learns of a family secret that makes him re-evaluate everything. Bayo and Temi have an intimate talk about their sibling relationship and rivalry. The fraying strings holding Kai's family together finally snap. Despite it all, the five manage to come together for one last moment of care-free childhood mischief and triumph. They are determined to remember this summer and mark their friendship in the annals of Bow.
