Tuvok becomes a reluctant nursemaid to three alien children from Drayan II, who have survived a crash-landing on one of their moons, as has he. Sent to die within a ritual, the children fear the morrok, a cave-dwelling creature who will come for them in the night as it already has for two of their number. Janeway, meanwhile, deals with adult Drayans, who are marginally polite but almost vehemently private and determined to reject trespassers on their sacred moon (the very moon, it would turn out, that Tuvok crashed upon).
