Wanneer Lisa's oefeningen met haar saxofoon de rest van de familie ergeren, wordt ze ontdekt door de hitparade-artiesten Billie Eilish en Finneas terwijl ze op zoek is naar een rustige plek. Billie nodigt Lisa vervolgens uit in haar studio voor een speciale jamsessie.
Nee, helaas is When Billie Met Lisa nog niet beschikbaar op Netflix in Nederland.
