"Twentica" is the first episode of science fiction sitcom Red Dwarf series XI, originally broadcast on the British television channel Dave on 22 September 2016, and made available early on 15 September on UKTV Play. The show again continued in its "classic" format of six standalone half-hour episodes, initially returned to in Series X four years previously. The crew are tasked with overthrowing a regime of time-altering cyborgs, who have travelled back in time and enslaved humanity, outlawing technology to prevent them from ever becoming a threat.
