Part 3/8:
Fast forward ten years into the mission aboard the spacecraft Humanitas, where the children are now young adults. Their daily lives are tightly regimented, punctuated by a blue liquid they drink, which shapes their behavior and attitudes. As they begin to understand more about their life on the ship and their mission's purpose, Christopher, one of the crew, becomes increasingly suspicious of the blue liquid's true effects. His concerns lead him and his friend Zac to uncover a shocking secret: they are being drugged to suppress their desires and emotional responses, thus preventing overpopulation.
