About
"A quiet, aching mystery about distance and loss"
An astronaut aboard the International Space Station goes silent after receiving a strange transmission, and back on Earth her family is thrown into a desperate, fractured search for answers. Told across shifting timelines, the show blends domestic drama with slow-building sci-fi dread, more interested in grief and marriage than spectacle. It's moody, deliberately paced, and compact, four tense episodes that lean on atmosphere and performance rather than action. The mystery unspools patiently, rewarding attention to detail over quick payoff, and the tone stays somber and intimate throughout rather than thrilling.
the tense, emotionally grounded performances anchoring an eerie space-set family mystery.
you want fast-paced sci-fi action rather than a slow, melancholic character study.
