Politieagent Danny werkt aan een antieke auto op de afgelegen ranch van zijn oom wanneer een zware aardbeving hem onder het voertuig vastklemt. Hij is gewond, alleen en kan niet om hulp roepen. Net wanneer Danny denkt dat de claustrofobische nachtmerrie niet erger kan worden, komt er iets gruwelijks tevoorschijn uit de spleten in de grond. Hierdoor wordt Danny gedwongen een meedogenloos gevecht te leveren voor zijn leven en zijn geestelijke gezondheid.
Nee, helaas is They Crawl Beneath nog niet beschikbaar op Netflix in Nederland.
