Shakespeare's Cymbeline

The show Cymbeline is about the king Cymbeline's children. His only daughter, Imogen, is supposed to marry the widowed queen's son, but she marries a lesser man named Posthumous instead. As a result of this, Posthumous is banished. Cymbeline also has 2 sons, that were stolen when they were babies and were raised by an old soldier in the mountain. In the end, Imogen and Posthumous are accepted as a couple under the king and the sons are told that they are royalty and the king's sons.
My favorite part of the show was when the queen's son and king's oldest song fought and the queen's son was decapitated.
