Dead-eyed and dumbly compliant, they wander around aimlessly with no idea of what the future will hold or their uncertain place in it.
Well, that's the Cuban Communist Party faithful...but in director Alejandro Brugues' amiable horror yarn the loyal party members find themselves even more brain-dead than usual.
'Socialism or death' reads the slogans but in this case it's more socialism and undeath.
Surveying this grimly gory state of affairs - dismissed by the official media as a US government ruse - idle wastrel Juan (de Villegas) laconically regards it as an opportunity to make a quick peso.
He gathers round him a team of crack oddballs, including his lecherous best buddy Lazaro (Molina), Lazaro's surf dude son Vladi (Perugorria) and his estranged daughter Camila (Duro) as well as a camp transvestite with a Rock-clone buddy who can't stand the sight of blood.
Juan's get-rich-quick scheme is simple - form a sort of 'rentokilazombie', a family firm which specialises in ridding families - by hammer, machete, catapult or paddle - of loved ones who have fallen victim to the zombie plague.
Brugues basically takes George A Romero's supporating template plus a side order of social comment and transports it to the sun-bleached streets of Havana, a decaying Spanish colonial warren that's the perfect fit for the crumbling undead.
De Villegas - who has the look of a youthful Ken Dodd - is a charismatic lead, a grisly opportunist who manages to make his character likeable despite a prediliction for viciously swatting lurching victims with a wooden oar.
The gritty city locations - from burning Soviet era tower blocks to even the sacred Revolution Square - are imaginatively used and zombie classics - ranging from the Caribbean-set Zombie Flesh-Eaters to Day of the Dead - are gleefully referenced.
It's good day-glo fun with a satirical edge whose playfulness never allows proceedings to get too earnest.
