There's No Such Thing as Zombies (2020)

In a world that’s deeply divided into zombie deniers and zombie believers, Carlotta, Colin and Paul are having a love triangle – only one of them is of the undead.
In a world where the media's unsure how to report about the zombie outbreak without angering the sponsors, Carlotta invites her ex Paul into her house, ignoring the fact that he's actually a zombie - much to the dismay of her husband Colin, who had (unbeknown to her) killed Paul in the first place.
