In this episode, Lisa falls for a musician named Brendan, which makes Nelson jealous, while Bart develops an interest in chemistry.
On a rainy day, the Simpson family goes to a STEM conference, where Lisa meets Brendan Beiderbecke (voiced by Ed Sheeran), a boy who is proficient in the piano, and falls in love with him.
The bullies are overthrown by Brendan, including Lisa's ex-boyfriend Nelson who tries to impress her musically at Phineas Q. Butterfat's Ice Cream Parlor, starting a conflict in her heart.
After Brendan says goodbye to Lisa, Nelson tells her he is relieved that she didn't choose him, as he needs to focus on his own skills before he can date her.
This proves that Bart is innocent, as Willie admits to spiking the vodka in an attempt to murder Principal Skinner.
When Marge offers to show him that movie as they have the DVD, Homer states that he would rather see X-Men: Apocalypse which everyone in the background is interested in seeing, except for Lisa, who'd like to see Moonlight.
When he heard Nelson sing in the sixteenth season episode "Sleeping with the Enemy," Long thought it was crazy but moving, and he want to draw from that pain.
But if you're going to do a parody of a lavish Hollywood musical love story (and, as the episode tag jokes, accidental momentary Oscar winner), you have to bring a lot more to the enterprise than is on display.
