Nothing is known about Samuels' life prior to or as the outbreak began except that she had a brother.
Samuels is one of the rangers alongside Victor Strand escorting Dakota to a safe house. When Ranger Terry's horse suddenly comes galloping up to the convoy, Samuels and Stand ride ahead to investigate. They find a tree that was chopped down to block the road and no response from Terry over the radio. Moments later, the horses of their fellow rangers stampede past them, prompting the pair to return to the convoy. They find the car empty and all of the escorts dead, having been murdered by Morgan Jones after they refused to defect from the Pioneers. Realizing how severely punished they will be if they return to Lawton without Dakota, the pair proceed to begin a search for their leader's sister. Eventually, they come across Alicia and Charlie and recruit them to search for Dakota.
Ranger Samuels accompanies Strand to Valley Town for a meeting with Morgan's group and the Outcasts on working together to face the uncertain threats of the Doomsday Cult. She first arrives outside the town gates on horseback alongside Strand as Sarah arrives as do Sherry and Rollie in the SWAT van. Inside Valley Town, she and the other visitors hesitantly hand over their weapons at the armory for security purposes. Later, she is at the wall when zombies start breaking in and prepare to help defend the settlement. At the end of the day, she and Strand return to Lawton, along with Daniel Salazar who has been welcomed to move into the community as he copes with his trauma and memory loss.
Samuels' fate is left unknown after she and the other residents evacuate Valley Town in search of shelter in an attempt to survive the impending devastation brought upon by the launched missiles at the hands of the doomsday cult.
