Star Trek 4

Six assignments in space and time.

In the name of the Federation Council and the Starfleet Command, Spock and the Enterprise crew grapple with:

A silicon-based monster
An interplanetary spy
An amorous Amazon
A misguided mobster "boss"
A time-jumping technician
And the mind-enslaving elders of Talos IV, the the "Hugo" Award-winning episode "Menagerie"
