Fan Casting Orbiter 9

For three years, her parents having died, Helena has lived alone in a spaceship, the only environment she has known. One unexpected day, she welcomes a young engineer named Álex, who has come to repair a detail. Having never had guests, she invites him to eat and falls in love. The latter, once out of the capsule, feels guilty... and, after reflection, decides to take her out and explain to her that nothing exists around her and that she is under surveillance as a guinea pig. She therefore discovers the true world which is completely unknown to her.
