At 90 years of age, William Shatner, the actor, finally gets to leave planet Earth after many years of portraying a starship captain. As he looks down at Earth through the capsule's window, he sits, overcome with emotion, while his crewmates are gleefully bouncing around enjoying their weightlessness. Perhaps it takes advanced age to be able to understand the deeper meaning of such a journey. This documentary enables us to experience it through the eyes of William Shatner, to understand why such a short trip into space means so much more than just getting high enough away from Earth's gravity to be able to float around.
