Rex, Cody, and Clone Force 99 (an unorthodox, elite squad also known as the Bad Batch), look to recover the Republic's strategy algorithm from Admiral Trench, but a haunting truth awaits. Believing that MIA soldier Echo may still be alive, Rex's mission becomes doubly important. Alongside Bad Batch, Anakin and Mavis, the clone captain launches a dangerous covert rescue. With Echo recovered, Rex, Bad Batch, Anakin and Mavis look to fight their way out of a Separatist base. The Republic plans a daring final strike against Admiral Trench, once again bringing together Rex, Echo, Anakin, Mavis, and the elite Bad Batch squad.
