Diani and Devine Meet the Apocalypse (2016) on Netflix

Plot summary

Gabe and Etta have been chasing a career in comedy without much luck. Then every power and communication system shuts off at once. Unprepared for anything of the kind, they gather their belongings and set out by road with their dog Watson and their cat Mrs. Peel, looking for somewhere safe to wait out a possible extinction event. Their struggle is with the mundane realities of the collapse rather than any grand catastrophe: no power, no phones, and people growing stranger. They try to keep their decency and their reason while the rest of humanity grows weirder around them.
