Chrysalis

When the sensors of the U.S.S. Voyager detect abundant
plant life on an unexplored planet, Captain Janeway leads an Away
Team in search of fresh food supplies. They find lavish gardens
inhabited by an enigmatic alien race that holds the gardens
sacred. The fragrent blossoms are beautiful, enticing -- and far
more dangerous than they appear. One by one, the Away Team begins
to fall into deep comas from which they cannot be revived.
Unwilling to spread the affliction to Voyager, the Away
Team is trapped on the planet until a cure can be found, but
their investigation is perceived as desecration by the devout
worshippers of the gardens. Pursued by a fanactical mob, slowly
succumbing to the insidious effect of the blossoms, Janeway faces
either a violent death -- or an endless sleep.
