Sibling rivalries rise to the surface in this weeks melodic episode of the musical comedy drama series, as Toyah and Aretha compete to write a song for top R&B star Monelle, played by former UK Eurovision entry Javine Hylton.
Toyah and Aretha set to work, each trying to compose their own song for Monelle. After many fruitless attempts, including one which sees Aretha rhyming shower with Chihuahua, the opposing sisters realise that they need to work together to make their tune pitch-perfect.
Elsewhere, a bemused Hadley tries to work out why all the fans seem to prefer Isaac.
Toyah is played by Naomi Battrick, Aretha by Dominique Moore, Hadley by Angus Harrison and Isaac by Matt Morgan.
