Not much is known about Cyndie's life before the apocalypse except that she may have lived in or around Washington D.C. before the outbreak, and that she also had a mother, brother and was close with her grandmother, Natania.
At some point in the outbreak, Cyndie, her mother, brother and grandmother, Natania managed to survive and began to build the community of Oceanside. After getting into conflict with the Saviors, Cyndie and the rest of the Oceansiders decided to rebel against them. However, the group failed, causing the execution of her mother, brother and numerous other residents. The remaining residents fled the community, in hopes to find a new home.
Since then, Cyndie, Natania and the other Oceansiders relocated to Oceanside Cabin Motor Court, where they have been peacefully living, and is firmly established with high security.
Cyndie first appears with Rachel in this episode, where they are walking the shorelines and come across Tara. She stops Rachel from killing her, and puts her under the shade of some junk on the sand, giving her supplies. She is later seen stopping Rachel from shooting Tara, and then being told to stand down by her grandmother. Cyndie is later seen at the table with dinner that night. The next day, Tara leaves the settlement with Kathy and Beatrice.
In the woods, Tara catches on to the real plan: Kathy and Beatrice are going kill her. Beatrice catchers her, but before she can pull the trigger, Cyndie tackles Beatrice to the ground.
“Run!” Cyndie yells at Tara. Cyndie catches up with Tara and makes her swear to keep her settlement a secret, to which Tara agrees. Cyndie gives Tara a backpack with food and water and offers to take her to the bridge where she last saw Heath. Cyndie accompanies Tara to the bridge and refuses to leave until Tara safely crosses. As Tara makes her way across the bridge, a herd of walkers emerges from behind a tarp. Cyndie shoots them down from the top of a car as Tara looks for Heath but is unable to find him. Tara watches as Cyndie is then found and taken back to Oceanside by Kathy and Beatrice.
Cyndie enters Natania’s home and suddenly Tara calls her out, as she holds her and Natania at gunpoint. She is angry and hurt that Tara broke her promise, but she says she had no choice and explains that her group is taking their guns in order to fight The Saviors. She begs them to talk to Rick Grimes, her leader, and join their resistance. But Natania refuses. Meanwhile Rick and the other Alexandrians set off the explosives near the Oceanside walls. Natania feigns an injury, distracting Tara, and giving Cyndie enough time to grab a hidden gun. Tara turns her gun towards Cyndie, and is tackled by Natania. As Cyndie holds her at gunpoint, Tara reveals that her own gun was never loaded. Natania asks for Cyndie's gun and she reluctantly complies.
As the other Oceansiders are taken captive outside by Rick and his group, Natania appears, holding Tara at gunpoint. Cyndie tells her people that Rick’s group wants to fight the Saviors. Beatrice suggests they join the fight but Natania refuses to lose more people to the Saviors. But then Michonne warns Rick that walkers are approaching. Cyndie knocks Natania out before she can shoot Tara. Enid, who was standing behind Natania, gun aimed and ready to shoot, stares in shock.
Rick’s group and the Oceansiders organize a combined defense that allows them to efficiently kill the walkers. Beatrice shakes hands with Rick. Natania angrily concedes, allowing Rick’s group to take their guns; but she remains adamant against fighting.
Cyndie informs Tara that she wants to fight with her, but Natania has forbidden her community to fight the Saviors. She thanks Tara for what her group is doing.
Cyndie is among the group of Oceansiders to inspect the truck brought to the community's outskirts by Aaron and Enid. When Cyndie finds Natania's body after she is shot in the head by Enid, she begins to mourn her grandmother's death.
