Dahlia reveals to Tao that Angela is being threatened by a stalker who calls himself "The Black Knight". Upon hearing this, Tao takes it upon himself to find the culprit. For the upcoming Cydonia Festival, Angela has agreed to appear as a secret guest for Ertegun. Meanwhile, Carole & Tuesday, eager to redeem themselves after their last disastrous performance at Cydonia Festival, are also making preparations. Finally, the curtain rises on each of their stages...

Following the weather plant terrorist incident, presidential candidate Valerie sees a sharp rise in popularity for her anti-earth immigrant rhetoric. Carole & Tuesday and Angela are nominated for Best New Artist Grammys, and Tao is suddenly taken into custody by the Mars Federal Attorney's Office after refusing a request from Schwartz. Meanwhile, Carole tries to make contact with the rapper Ezekiel, who she believes is her childhood friend Amer from the orphanage.

With Tao under arrest and her mother Dahlia in a coma, Angela is left feeling alone like never before. The Mars Grammys are to take place on Christmas, Carole's birthday. Carole & Tuesday rack their brains for the perfect song to complete their album, while Gus runs around trying to organize a special guest to co-perform with them. Carole also goes to see Amer to convey her feelings before he's deported back to Earth.
