Upon her return from a deep-space mission, Janeway startles Chakotay with her plans to hand over the ship's warp core to the R'Kaal collective. The Captain's willingness to part with such a crucial piece of Voyager's technology without a fight disturbs Chakotay, who turns to the Doctor for help. The hologram insists that Janeway is mentally sound. Chakotay, though, remains skeptical, and soon has even more reason to question her actions.
