Conspiracy

Picard suspects a large-scale conspiracy when he witnesses strange behaviour among Starfleet's high ranking officers.

This is a great one! Those critters craw into people and take them over. The best from season one.

Neutral Zone

A 20th century probe carrying three cryogenically frozen humans is detected by the Enterprise while en route to the Neutral Zone to confront Romulans.

This one is also great!
