Barbra (1968)
She and her brother Johnny drove three hours to a cemetery in order to visit their dead father at their mother's request. There she is attacked by a shambling stranger and when her brother tries to defend her, he dies in front of her. Barbra flees to a nearby house where she finds a weapon. She attempts to flee the house after finding a corpse inside but runs into a fellow survivor, Ben.

She soon descends into a catatonic state, leaving Ben to fortify the house. She manages to recount the events in the cemetery but soon becomes agitated and confused. When she attempts to leave the house in search of Johnny, she strikes Ben and he retaliates with a blow that knocks her unconscious.

When she regains consciousness, Barbra becomes quiet and withdrawn. She attempts to defend the house against an incoming horde of ghouls but she is overwhelmed by their numbers and dies offscreen.

Barbara (remake)
In this version she visited her mother's grave with her brother Johnny. She was also attacked by a zombie and witnessed her brother's death, when he saved her.

However, in contradiction to the original, she proved in the remake that she was a strong character and, as such, she began to work actively regarding the Zombie threat to the extent of even leading the group once Ben helped her get over with her brother's death and guided her while after the same time even acting as a team with him.

She was also the only one who managed to survive by escaping the house. After that she reached and joined a group of locals who were hunting Zombies. There she realized she is safe, but must also realize they have killed his brother who had become a zombie though she also understood it. Later she is disturbed by the sadism shown by the locals against the zombies, who, instead of killing them, mistreated them before killing them.

When they reached the house Ben, who had become a zombie was killed, while she killed Harry because of his decisive role in this while making it appear, as though he was a zombie, too. After that she watched the dead zombies being burned by the locals.
