Jem and the Holograms (2015)

Teenager Jerrica (Aubrey Peeples) is an extremely shy but talented singer-songwriter whose dreams of stardom come true when she forms the group Jem and the Holograms. Other members include her younger sister Kimber (Stefanie Scott) on keyboards, drummer Shana (Aurora Perrineau), and bassist Aja (Hayley Kiyoko). With help from Rio (Ryan Guzman), the son of the CEO (Juliette Lewis) of Starlight Music, the four young band members find their own voice while taking the world by storm.
