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.

Carole and Tuesday are an instant sensation. But fame has its drawbacks, and they face tough choices about the next stage in their career.

Going indie means finding people themselves. Gus persuades the legendary and very strange Tobe to work with the duo. Angela enters the studio.

After their debut single's release, the duo get an invitation from a reclusive living legend. Tuesday's mother takes the stage for a campaign debate.

The single charts, and Gus decides they'll play South by Southwest. On the way home from rehearsal one night they meet Carole's childhood idol, Flora.

One morning, Ertegun wakes up bankrupt: his AI manager stole all his money and vanished. Carole and Tuesday enter the studio, but Tobe's not happy.

While Ertegun and Tao squabble over her single, Angela tries to deal with a stalker. Tuesday meets with Kyle as her mother's campaign heats up.

Tao offers to track down Angela's stalker once Dahlia tells him all about it. Things come to a head as Angela takes the stage at the Cydonia Festival.

Carole and Tuesday start rehearsing for their performance as Mars Grammy nominees. Tao runs afoul of the law just as Angela's replica is completed.

With Tao arrested and her mother hospitalized, Angela is all alone. Carole and Tuesday struggle to come up with a song to close their album.

After Skip gets arrested, the duo and their industry colleagues decide to create a supergroup song opposing Valerie's policies. Tao is still at large.

Tao appears to tell Angela the truth. With Carole & Tuesday's first album finished, the supergroup performance is scheduled for New Year's Eve.
