When an away team is threatened by some storm, Archer is forced to collect them by transporter. Especially Ho Shi is still very reluctant to accept this vehicle, and for a good reason, as it would seem for a moment: In the days following the transport she finds herself exceedingly „invisible“, being ignored by fellow crewmen and eventually even by doors. When she finally disappears in a translucent parallel universe, she is instead able to see aliens who are about to booby-trap Enterprise, aliens invisible to the rest of the crew. She finds a way to contact the living, but apparently too late. When the aliens use their transporter to escape from the ship, she overcomes her fear of the things and follows them, only to learn that it was all a dream.
