The movie Survival of the Dead, directed by George A. Romero, was officially released.
A widespread zombie outbreak begins, causing society to collapse and turning people into the undead.
A group of survivors led by Sarge arrives on Plum Island seeking refuge and confronting local landowners who have opposing views on how to handle the undead.
The two feuding families, the O'Flynns and the Muldoons, reveal their opposing philosophies: the O'Flynns aim to exile or kill the infected, while the Muldoons keep their infected family members isolated in hopes of a cure.
Irish Muldoon is revealed to be a zombie kept alive by his family, leading to increased tension between O'Flynns and Muldoons.
The O'Flynns and the Muldoons engage in violent confrontations over the treatment of the infected family members.
Sarge attempts to mediate the conflict and protect the survivors from both the undead and the hostile families but tensions escalate.
A final violent confrontation ensues between the O'Flynns and Muldoons, resulting in significant casualties and destruction.
Irish Muldoon transforms into a full zombie, which intensifies the stakes for both families, forcing critical decisions about the nature of the undead and humanity.
After the battle and chaos, Sarge and the remaining survivors escape Plum Island, reflecting on the cost of survival and the unresolved conflict.
