Last Ones

"A cataclysm has transformed the Earth's atmosphere, blocking out all ultraviolet light, plunging it into a new ice age, and giving vampires free reign across the planet. With the human race threatened with extinction, two adults and a handful of children struggle to survive, hidden in the rubble of a ravaged Spanish city. Led by a mysterious savior who joins them, they embark on one last, desperate gamble to cross Europe in search of refuge, to where the last of humanity is gathered."
