A girl sings a song, and her father is sacrificed.  A son is tasked with taking his mother to the mountains, where she will left to die.  A tense hostage situation at a sumo wrestler's dojo.
He simply remained silent and bowed...
bajó la cabeza y se quedó callado.
así que bajó la cabeza 
y se quedó callado.
Ele simplesmente ficou em silêncio
 e abaixou a cabeça.
