On the night of a festival, the Marker duo Walsh and his daugher Lynda return, and Memempu receives a surprising gift. Will she finally be allowed to pursue her dream?
This is Underworld, a world encased 
in solid rock where light never reaches.
نحن في العالم السّفلي، عالم مُطوّق بصخور
صلبة حيث لا يصل النّور أبداً
Dies ist Underworld,
Pero estamos en Underworld y la luz
del exterior nunca llega tan profundo.
Pero estamos en Underworld y la luz del
exterior nunca llega a esta profundidad.
Ici, c’est le monde souterrain,
Insomma, questo è l'Underworld, un mondo circondato 
da dura roccia dove la luce non arriva mai.
Aqui é o Underworld, um mundo coberto por 
pedras duras, onde a luz  nunca chega.
Мы же с вами в Андерворлде.
