The crew of the USS Discovery are really settling down and starting to enjoy their new life in the 32nd century — fixing some butterflies’ GPS network, giving a commencement speech to some socially-distanced Starfleet Academy students, and fixing the unexpected and alarming angular velocity of a Federation space station. Then suddenly an unimaginable tragedy strikes.
