Silversun follows the journey of the titular spacecraft, two years into a ninety-year journey to a distant, Earth-like planet, intended for colonisation. The colonists are in cryogenic status, and the ship's crew is largely teenagers, who will take over the primary roles as the adult crew ages.
The program's focus was a combination of the coming-of-age/interpersonal relationship storylines typical of a teenage show and the type of ethical dilemmas common to science-fiction story-telling. Among the latter were such issues as whether or not a crew member's clone was human, and what effect long-distance interstellar travel would have on the human mind and emotions.
Season two of the program ended on a cliffhanger, and no plans have been made to revive the program.
