The first season of Dark Matter explored the mysterious pasts of the main characters as well as their past and present relationships with each other.
Dark Matter told the story of six people on a spaceship called the Raza who awoke from suspended animation with amnesia.
Unlike other shows in its genre, Dark Matter had yet to introduce viewers to aliens, which would have made the story they were setting up for season 4 new territory for the series.
