Intersound

In 1999 an alien spaceship crashed onto the earth. Hidden on board were the secrets of a unique science known as Robot technology. Databanks found in the ship were transferred to the Earth Robotech Computer Complex. In 2009, an alien search party arrived from hyper-space to reclaim their lost databank. The united Earth Government was forced into an Inter Galactic war. Earth forces were able to win the first battle... but at a great cost. The planet was virtually destroyed. New population centres grew out of the ashes... It is now 2027, a second armada sent by the aliens is nearing earth, they have come to recapture the secrets of their lost technology and then destroy the Earth.

Robotech II: The Sentinels was an attempt to continue the original 1985 Robotech television series. The project was cancelled in 1986. The aborted Sentinels series would have followed the ongoing adventures of Rick Hunter and Lisa Hayes and the rest of the Robotech Expeditionary Force (REF) during the events of The Robotech Masters and The New Generation series.

Jankovics's adaptation of the eponymous play is divided into multiple parts, and depicts the creation and fall of Man throughout history.
