In the search for arms and artillery, Captain Rex brings the rebels to an old abandoned base from the Clone Wars. They quickly find that they're not alone, however, and must once again face enemies from the past.
Hera and Sabine dropped Ezra, Kanan, Zeb and Chopper off on Agamar where stood the wreckage of an old transport ship once used by the Separatist Alliance. Following Rex’s lead, the Rebels hoped to find a huge supply of weapons and explosives for the Rebellion. They arrived at an opened hanger and soon found a supply of proton bombs, enough for the Rebellion’s fight against the Empire. All, except Chopper, were about to gather them when they suddenly got trapped inside a ray-shield. Then, to everyone’s surprise, a group of Separatist battle droids appeared and surrounded them. They were prepared to kill the Rebels, mistaking them as members of the Republic, but received new orders from their commander to bring them in alive. Then they rendered them unconscious using a stunner.
Later, the Rebels regained consciousness and found themselves in the commander center. Standing before them was a Super Tactical Droid known as General Kalani, and learned from the droid that prior to the shutdown command of the entire droid army Kalani and his forces avoided it after assuming it was a Republic trick. Despite telling the droid that the war over, Kalani had a plan to end the Clone Wars with a victory for the Separatist Alliance. He challenged the Rebels to a battle against his forces with Zeb as the hostage they had to save. Even though Kanan and Rex refused Ezra accepted Kalani’s challenge in exchange for Zeb’s safety and the proton bombs. Even Kanan and Rex agreed to go with it. As the droid army took up their positions, Chopper found a separatist’s shuttle and sent out a distress call. Meanwhile, Hera and Sabine were being pursued by Imperial forces after being ambushed during a supply run. Leading the pursuit was Governor Pryce. At the same time, the Imperials received Chopper’s distress call from the Agamar System before the Rebels did. Governor Pryce gave orders to locate the nearest Imperial outpost to Agamar and Deploy them.
Back on Agamar, the battle between the Rebels and the Separatists was about to begin. Listening to Kalani’s instructions, the Rebels had to fight their way back to the command center and capture it to free Zeb. Kanan volunteered Rex to lead the way since he had more battle experience than the rest of them. Rex’s plan was to get inside the hanger first, and warned them that Kalani had the advantage over them in numbers and firepower. Their only chance of victory was to put him on the defensive by going in aggressive and use the element of surprise. The droid army marched out of the hanger and the battle began. The droids opened fire and Ezra and Kanan deflected their attacks, giving Rex the cover he needed to take them out with thermal detonators in hopes of scattering their numbers. With the droids scattered the Rebels fought their way to the hanger and took cover behind a crate. The hanger looked clear but Rex advised caution. General Kalani observed the battle from the command center, and when he noticed the Rebels on the move he ordered the destroyers to be deployed. The destroyers showed up on the catwalk and opened fire on the Rebels. They took cover behind another create. Ezra noticed a crane on the other side of the hanger, which gave him an idea to take out the catwalk and the droids. While Kanan and Rex distracted the destroyers Ezra sneaked pass them to the crane, unaware that Kalani is watching. He then ordered more droids to move in. Ezra reached the crane, and using The Force he ramed it into the catwalk, taking out both the destroyers and the droids. The Rebels regrouped and fought their way to the command center. Ezra began to notice that both Rex and Kalani were taking this battle to heart; both were determined to gain a victory.
They soon made it back to the command center, only for Kalani to reveal his deception. Rex almost shot the droid, but Ezra stopped him and stood in-between the two enemies, stating that neither of them won this battle. Listening to Ezra’s reasoning, the Clone Wars came to a suspicious end with no clue over who won; the Republic or the Separatists. All he knew was that the Jedi were wiped out, the clones were decommissioned, and the droid army was simply shutdown, but who really won was a good question. During a moment of silence, they later noticed Imperial forces had arrived and have deployed Stormtroopers and walkers to intercept. This made Ezra realize that the real victors of the Clone Wars was the Empire. The clones and droids fought one another and when they were weak enough the Empire took over. Understanding Ezra’s logic and reasoning, both General Kalani and Rex agreed they were both on the same side and their true enemy was the Empire.
Working together, the Rebels and the droids conjured up a plan to escape using the three shuttles that Chopper found. However, the odds were against them. Kalani’s droid army was depleted, the shuttles had no weapons, and they did not have the firepower to take on the walkers. But then Kanan brought up the explosives they originally came for, giving Rex an idea. They would roll them into the feet of the walkers and blow them up, giving them the time they needed to escape. To set them off, the droids would deliberately fire at Ezra and Kanan to redirect their plasma bolts towards the bombs since they were not accurate. With the plan set, the Rebels and the droids proceeded. The droids, led by Zeb, moved in and attack the scout walkers and troopers, giving them the time they needed to roll the proton bombs at the AT-ATs. On Kalani’s orders, five of his droids fired at Ezra and Kanan, who both redirected their blasts at the bombs, setting them off and destroying one of the walkers. Then they made a retreat to the three shuttles and flew out with only one shot down. The Rebels and the Droids had escaped.
Both sides congratulated one another for their victory, but most of the credit went to Ezra. Because of him, he made them realize that neither one of them were meant to win the war and could have brought it to an end with a victory for both sides. General Kalani bidded the Rebels fair well and the two shuttles went their separate ways. The Ghost was waiting for the Rebels in orbit. Kanan informed Hera that they failed to get the explosives but were successful in getting a new Phantom.
