Mission 216 on Nebula. Second trip to Black Hole 186. Rescue mission 16298... Audrey Murphy and Stephen MacGlance are going to Black Hole 186 not to explore, but for a rescue mission. Audrey's husband, Pete, was believed to be trapped there, desperate for help. As Audrey and Stephen lift off in the safest spaceship, Nebula, Audrey wonders if Pete would approve of her choice to date Stephen. After all, there is no proof of Pete's life: Audrey and Stephen can only find out one way by going into the most dangerous black hole ever seen in history, Black Hole 186. Suddenly, Audrey loses everything. With the ship damaged and Stephen's soothing voice no longer by her side, would she be able to see Pete again, or would this all be a fatal mistake?
