It’s a movie about Keenan and Kel working at Good Burger in their mid 40s. They have mental trauma so they regularly call radio psyciatrist Fraiser Krane.
Keenan and Kel never meet Fraiser, but half the movie is Keenan and Kel, and half the movie is Fraiser. They’re regular callers, and screaming in agony in the world that is 2025.
They already made Good Burger 2 about Ed and Dexter as adults with children.
