Wanneer een hechte vriendengroep samenkomt voor de bruiloft van Skylar en Dan, hebben ze nog geen idee dat ze getuigen zullen zijn van een serie catastrofale gebeurtenissen die de feestelijk dag zullen veranderen in een strijd om leven en dood. Ze moeten op zoek naar een veilige plek en zien te overleven terwijl een leger aan creaturen, waarvan ze het bestaan niet kenden, de allesomvattende vernietiging ontketent.
