This episode involves Janeway realizing that 3 of the crew have pretty much "fallen through the cracks". One is an anti-social jerk with a high IQ, one is a hypochondriac and the other is a Bajoran girl who always struggles with the math and has little self-confidence.
Under normal circumstances these 3 would have been transfered off the ship, but since they are stuck in the Delta Quadrant, they are also stuck on Voyager. Realizing that all 3 of them have never been on an away mission, Janeway takes them on the Delta Flyer on a routine study mission. As you can imagine, things don't go according to plan.
The FX shots in this episode stand are really well-done. Someone put in some over-time getting the neat close-ups of Voyager in the opening bit.
This episode also features a cameo from guitarist Tom Morello (Audioslave & Rage Against the Macine) as crewman Mitchell.
