The mid-season finale opens with a handful of unknown survivors fighting their way through the woods, attacked by a pack of walkers. One of the survivors is bit, and the group is conflicted on whether to help her along. They manage to make their way across a demolished brick wall and towards the prison.

In Woodbury, Andrea is putting herself together and finds a photo of the Governor, his wife and daughter. The Governor approaches and remarks how Woodbury is starting to grow on her.

In the Governor's office, he opens a caged door and calls for his walker-daughter, Penny, to emerge. She does, growling with a pillowcase over her head, and he tries to soothe her to no avail. Angry, he shoves her back into her cell.

Meanwhile, Glenn and Maggie have been reunited. Glenn asks what the Governor has done and she assures him that he barely touched her. Glenn is topless, having given his shirt to Maggie, and breaks off a walker corpse's arm. After some effort, he wordlessly hands a bloodied and sharp-edged bone to Maggie.

Outside of Woodbury, Rick, Michonne, Daryl and Oscar are huddled and strategizing their next move. The Governor and Merle are also strategizing against Rick and his team. The Governor suggests a fake surrender like they did with the National Guard and tells Merle they won't hurt his brother Daryl.

Rick's group successfully makes their way into the settlement with Michonne's guidance, but the men are wary that she is leading them into a trap. A Woodbury resident unfortunately finds his way to Rick, who holds a guy to him, asking where they could find Glenn and Maggie. The man is no help so they knock him unconscious.

Back in the prison, Axel watches Beth rock the baby and asks how old Beth is. Carol overhears and takes Axel aside, telling him to stay away from Beth. Axel says he's been alone for too long and assumed Carol was a lesbian (due to her cropped hair). Bemused (and probably disgusted), Carol walks away.

Glenn and Maggie are trying to fight their way out of their holding cell past Merle, and shots are fired. Rick and his team overhear, as more of Woodbury's armed men run into the cell to help Merle. The two groups finally convene, and Glenn and Maggie are successfully taken by Rick and his team.

Andrea, the Governor and the rest of Woodbury have also heard the gunshots and are on alert. The man who was knocked unconscious has finally come to and recounts how he was attacked by a group of unknown men.  The Governor calms his citizens, encouraging them to return to their homes. However, he is aware that Woodbury is under attack and relays this to his armed men.

Rick and his team race through the streets of Woodbury and seek refuge in an empty building. Michonne goes rogue, while Glenn and Maggie recount what transpired since their capture. Rick suggests they retreat back to the prison, but Daryl is hesitant about leaving without seeing his brother. Rick is adamant that he needs Daryl by his side, to which Daryl agrees.

The Governor and his team convene – Merle wants to "take out" Rick's group, convincing everyone that they killed Warren. Milton is concerned the perimeter has been breached, the Governor asks Andrea to patrol the residences. Peeved, because she thinks her time is better spent in battle, she agrees.

Michonne has found her way to the Governor's office, sits in a chair alert, waiting for someone to enter.

Outside, gunshots are fired as Rick and his men struggle to escape Woodbury against its sentinels. Andrea has also pulled out her gun, shooting at them. Through the smoke, Oscar is struck while Rick sees Shane walking towards him, eventually shooting him. Upon closer examination, it's actually not Shane. Maggie screams for him to run, and he does.

In the prison, Hershel, Carl and Beth are in the cell block when they hear screams. Carl convinces Hershel to allow him to investigate. In the dark tombs, he comes across a group of survivors fighting against a pack of walkers. He helps them, shouting at them to follow him to safety.

Michonne hears a noise behind a door in the Governor's study, and barges in. She finds the aquarium tanks filled with human heads. Revolted, she turns her attention to the cage where walker-Penny is held captive. Upon seeing a little girl chained with a pillow case over her head, Michonne is immediately concerned, releasing walker-Penny. Only when Penny is unmasked does Michonne realize her mistake and aims to strike Penny just as the Governor walks in with a gun, shouting "No!"

The Governor removes his weapons, begging Michonne not to hurt his daughter. Michonne is clearly unmoved and lunges her katana through Penny's skull. The Governor attacks Michonne. As they fight, Michonne is pushed into the aquariums and they shatter to the ground, an undead head rolling to the floor, its jaw snapping. She grabs at a glass shard and stabs the Governor in the eye. Before she has a chance to kill him, Andrea comes in with a gun drawn to Michonne.

The two friends angrily stare each other down before Michonne lowers her weapon and walks away. Andrea goes to the Governor's aid, staring at the aquarium of heads and finally turning her attention to the Governor who is weeping and cradling Penny's body.

Back in the prison, the female survivor who was bitten has died. Her friends are held captive by Carl who promises them safety, food and water. Another female is angry at being locked up, but the male leader, Tyrese, consoles her, relieved to be safe.

In the hospital ward at Woodbury, a doctor examines the Governor's eye. Andrea comes in, wondering why Michonne tried to kill him and asking about the aquariums and Penny. Milton and Merle interrupt, and the Governor reveals that he was attacked. Merle promises to go after Rick's group in the morning.

The mid-season finale concludes with Rick and company racing away from Woodbury. Michonne rejoins several of them outside the wall, and Rick disarms her, questioning her about her whereabouts. She tries to convince him that they need her to get safely home to the prison and/or to retrieve Daryl.

Inside the wall, the Governor addresses the citizens of Woodbury, blind in one eye. As he announces how Woodbury has been breached by terrorist, he accuses Merle of leading them in. Daryl is dragged into the arena, coming face to face with Merle and the rest of Woodbury. The citizens are riled up and start screaming, "Kill them!"
