When Astronaut Troy Holloway (OGG) wakes up to find himself trapped aboard a drifting escape pod shooting towards the Sun, he quickly realizes the true terror of his situation. With rapid oxygen depletion and a burn-up rate of 90 minutes, the main ship’s Commander Roberts (LOWE), leads a rescue party to save Holloway before time runs out. Having recently lost his son and now confronted by his immediate end, Holloway feels less enthusiastic about survival. But Roberts, speaking to him only through a weak radio transmission, is determined to save his life, and both soon learn that the lives they have lived influence each other in unexpected ways.
