Energy beings from a nebula displace Chakotay's consciousness from his body. The Doctor pronounces him brain-dead and B'Elanna turns to Chakotay's cultural beliefs to try to bring him back. Meanwhile, Chakotay's spirit roams the ship and infiltrates crew members in an attempt to warn his shipmates of the dangers of the nebula, but they mistake his efforts as a malicious alien manipulation.
