Future Boy Conan (1978)

Season 1: Episode 12

Lana and Lao descend to the Triangle Tower's Core Block to acquire the IC chip they need to repair their flyer. While Dyce and his crew - minus Jimsy, who refuses to abandon Conan - turn tail, Conan frees some prisoners who have rebelled against Lepka, and together they search for Lao. Luke, the leader of the prisoners, leads Conan and Jimsy to the Core Block, but Lepka and his soldiers arrive there as well. With the help of the ex-prisoners, Conan's group escapes the Core Block and heads to High Harbor, with Dyce and his crew joining them along the way.
