On November 6, 1985, an M-19 guerrilla commando forcibly entered the Palace of Justice and took more than 300 people hostage, including Supreme Court justices. On November 7, the Colombian Army retook the Palace. Inspired by real and publicly known events, the series recounts what happened during the siege and retaking of the Palace of Justice, which resulted in the deaths and disappearances of at least 94 people, including justices, guerrilla members, civilians and members of the military. It also follows the victims' families in their pursuit of justice for more than 20 years.
