Star Trek

For the life of me, I can't find a pic or a link from any online searches, but I distinctly remember a STAR TREK IV : The Voyage Home poster with something along the lines of...

The crew of the Enterprise take their most important journey...home.

Can anyone confirm if :

a) this was a tagline for the 4th flick?

b) the full and correct tagline?

Thanks in advance.

Never heard that one...

There were two primary taglines for the film that I am aware of (at least for the US release of the film):

1. Stardate 1986: How on Earth can they save the future?

2. The key to the future can be found only in the past

A quick google search did not reveal anything resembling what you suggested.
