Star Trek: Voyager

When the sensors of the USS 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 fragrant 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 fanatical mob, slowly succumbing to the insidious effect of the blossoms, Janeway faces either a violent death - or an endless sleep.
