The Cloud

Plot:

With power reserves running low, the crew of Voyager alters course to enter a nebula in which there is a usable power source or "coffee" as Captain Janeway puts it. However, once they enter the nebula they encounter numerous problems; they are attacked by an unknown substance that cripples every defense system on the ship, forcing the crew to retreat out of the nebula, losing 11% of their power reserves. The crew later discovers that the nebula was not a real nebula, but was in fact, a life form. The crew returns to the nebula to help the creature recover after the damage that they caused while trying to escape from it the first time. This episode is the first time that viewers are introduced to 'Sandrine's', a holodeck program created by Tom Paris.
