The story of a young group of siblings pretty much abandoned by their parents, surviving by their wits - and humor - on a rough Manchester council estate. Whilst they won't admit it, they need help and find it in Steve, a young middle class lad who falls for Fiona, the oldest sibling, and increasingly finds himself drawn to this unconventional and unique family. Anarchic family life seen through the eyes of an exceptionally bright fifteen year old, who struggles to come of age in the context of his belligerent father, closeted brother, psychotic sister and internet porn star neighbors.

本季将紧接第一季的结尾展开，重点描绘坦格利安家族的内战“龙之舞”。两百年之前的坦格利安王朝动荡期，一场围绕王位继承引发的家族内战在此刻悄然酝酿。当老国王韦赛里斯一世驾鹤西去，合法继承人雷妮拉公主却未及奔丧，这无疑为野心家打开了篡权之门。曾与雷妮拉情同手足的第二任王后阿莉森怀有私心，隐藏国王逝世的秘密，趁乱宣称国王遗愿变更，将自己与韦赛里斯所生的儿子伊耿推上了王座，此举宛如投下一枚震撼宫廷内外的重磅炸弹，引发了剧烈的连锁反应。这一转折非但导致了两位昔日姐妹的友谊破裂，更将整个国家拖入了一场无法调和的分裂危机，从此分裂为坚守雷妮拉公主权益的“黑党”与拥护阿莉森及其血脉的“绿党”两大阵营，二者之间的对立格局愈发明显。
