My current draft, obviously subject to change:

RETURN OF THE JEDI

The rebellion stands on the brink
of destruction. The GALACTIC
EMPIRE has begun construction
on a new armored space station
even more powerful than the first
dreaded Death Star.

As the rebels gather in preparation
for a last-ditch offensive against
the Empire, Han Solo is imprisoned
by the vile gangster Jabba the Hutt,
and Luke Skywalker remains
with Yoda to complete his Jedi
training.

Unwilling to await Luke's return any
longer, Princess Leia has rashly cobbled
together a desperate plan to rescue
the man she loves, while the Emperor
sets into motion his own plot that could
spell certain doom for the rebels. . . .

I'm still not 100% happy with it, but that's what I've come up with so far. I won't start work in earnest on ROTJ until SW and ESB are finished (and even that will be a pre-Revisited rough draft), so I've got quite a while to worry about this.
