Group marriage is portrayed as a perfectly normal, if atypical, lifestyle choice on Caprica, at least among Athenian devotees and clergy. Homosexuality, gay marriage, and adoption by same sex couples are all depicted as a normal and seemingly non-controversial part of Colonial culture.
One of the main characters, Sister Clarice Willow is in a group marriage with at least four husbands and three wives.
Two families, the Graystones and the Adamas, live together on a peaceful planet known as Caprica, where a startling breakthrough in artificial intelligence brings about unforeseen consequences. A spin-off of the Sci Fi Channel series "Battlestar Galactica" set 50 years prior to the events of that show.
