In the shadow of their famous brother, Bruno Mars, The Lylas move from Hawaii to Los Angeles to make a name for themselves.
The Lylas argue with their manager over a failed meeting with a high profile music producer. Tahiti, Tiara & Presley settle into Jaime's house but feel smothered & secretly sign a lease on a home without Jaime.
A surprise visit threatens to derail the sisters' first show. Tiara slams Tahiti for slacking. A famous vocal coach tells the sisters their singing is awful, while the rift with Ben continues to grow.
Nerves run high during The Lylas' first live show in Hawaii. But the jitters don't end as they land a second gig in L.A., only two days later. Ben and his ego cross the line and the girls have had enough.
After a tragedy strikes, will the girls find the strength to go on?
Grieving over the sudden loss of their mother, The Lylas are unable to sing and struggle to keep their band intact. They decide to do something their mom was against in her honor.
The Lylas go into the studio with a new song written by their brother, Bruno. A former Pussycat doll teaches them choreography, but a fight over who will sing the lead pushes the group to its breaking point.
The Lylas complete their newest song, Voices in My Head, but will it be good enough to meet Bruno's standards? Meanwhile, the band is in flux.
