Train to Busan director Yeon Sang-ho returns to the zombie thriller with a larger, similarly striking tale of a group trapped in an overrun skyscraper.
A biotech company conference quickly derails when an ex-employee unleashes a mutated slime mould, creating a hive-minded, fast-learning zombie horde he controls. As the outbreak gets locked down to an adjoining mall, a shaken band of survivors forms to stop him, led by a righteous ex-professor – but mounting tensions and the horde’s intelligence complicate things.
Years after enlivening the genre with a tight, novel new setting, Yeon expands on its bleak but riveting vision with a larger field and less familiar monsters. Convincing and sharply-written characters make the struggle to survive matter - and all the more excruciating against zombies that are not only horrifyingly agile, but clever and interlinked.
