Small town girl Tuesday takes the midnight train to Alba City, leaving home for her dreams. There, she sees city girl Carole singing on a bridge.
Top producer Tao begins working with Angela, who's yearned for a music career. Carole and Tuesday sneak into a concert hall to practice their song.
With some trepidation, Carole and Tuesday agree to take Gus on as their manager. He hatches a plan to get them featured by the famous DJ Ertegun.
Gus's next plan to get Carole and Tuesday their big break is to make a music video. He buys a weird film directing bot and asks his ex-wife for help.
Tuesday's brother Spencer heads to Alba City to search for her. Gus implements Plan C: gigging for exposure! Starting with a one-song gig at a bar.
Gus somehow gets Carole and Tuesday a gig on the main stage at a huge festival. The catch: they're a standby act for the famous, difficult Joshua.
If new media fails, go old school! Gus gets Carole and Tuesday to try out for the amateur singing show, Mars Brightest. Tao wants Angela on it too.
The duo make the cut for Mars Brightest, along with Angela and a Tuesday mega-fan named Cybelle. Now they just have to perform their very best!
Carole and Tuesday attend the Mars Brightest broadcast on their day off. Before she faces Angela, Cybelle makes a startling request of Tuesday.
The Mars Brightest semifinals begin with Ertegun as guest judge. Tao tells Angela to change her song, and Cybelle's visit raises Carole's suspicions.
With Tuesday injured, she and Carole frantically try to think of a piano-only song they can perform. The attack incites recriminations backstage.
It seems like all is lost, but Gus encourages Carole not to give up. With time running out before the final, they launch a rescue operation.
