Bancroft offers him the chance to solve a murder-Bancroft's own-to get a new shot at life. In the first season, set 250 years after the Envoys are destroyed, his stack is pulled out of prison by 300-year-old Meth Laurens Bancroft, one of the wealthiest men in the settled worlds. Takeshi Kovacs, a political operative with mercenary skills, is the sole surviving soldier of the Envoys, a rebel group defeated in an uprising against the new world order. Only the wealthiest, known as "Meths" in reference to Methuselah, have the means to change bodies through clones and remote storage of their consciousness in satellites, so they never have to die of old age before being resleeved. Physical human or synthetic bodies are called "sleeves" and stacks can be transferred to new bodies after death, but a person can still be killed if their stack is destroyed and there is no backup. These storage devices are of alien design and have been reverse-engineered and mass-produced but can only be made from the material on Harlan's World. In the future, a person's memories and consciousness (termed digital human freight, or DHF) are recorded onto a disk-shaped device called a cortical stack, which is implanted in the vertebrae at the back of the neck.
