Ark One, a spaceship on a journey to find a new hospitable planet for humanity, suffers an unexpected disaster that causes massive loss of life. Short on supplies and its leaders dead, the remaining crew must band together if they want any chance of survival or a successful mission.

The crew struggles to establish a sense of order on the ship. Two investigations uncover more questions than answers.

The Ark’s engines are down and it’s running low on drinking water, so when the crew learns an oncoming asteroid is hours away from impact, it seems that all hope is lost.

When the crew suddenly begin hallucinating, their psyches are put to the test by memories of the past while they simultaneously race to figure out what’s causing their mysterious symptoms.

As a radiation leak sparks crisis, there’s a break in the murder investigation. Someone will have to sacrifice themselves for any hope of survival.

After identifying a planet rich in much-needed fuel, the crew devises a plan to whip around a nearby star to reach it, but things don’t go according to plan.
