"The story opens aboard the multi-national space station Observation in orbit above Earth in the year 2026. An unknown event has crippled 'Observation', leaving it without power and spinning. Dr. Emma Fisher, the stations medical officer, tries to restore contact with Houston as well as other five members of the crew to ascertain what has happened, without success. She manages to reboot the stations integrated AI, SAM (Systems Administration and Maintenance) which controls the station's systems and functions, and is the role the player assumes. After performing basic diagnostics to find out what happened, SAM receives a transmission of unknown origin, containing co-ordinates to an unknown location. The station then begins to tremor violently with a deafening sound. SAM becomes unresponsive to Emma while being influenced by the signal, causing strange glyphs to flicker on his interface, and with instructions to 'BRING HER' appearing."

Note: It is more than hinted at towards the end that Dr. Fisher and SAM are merged into one being, after innumerable attempts in different timelines. Why the mysterious (alien?) interference wants this is not explained.
