In this sci fi adventure a shape shifting female alien fools
an ancient killing android and an nearly immortal vampire well enough
to escape having her soul drained.
She saves the universe from this ancient dreaded race
by assuming the shape of one of them for long enough to kill
the powerful alien.
The special effects and sets are pretty good and the plot and dialog aren't entirely bad, but it is definitely a 'B' sci fi with suggested sex and violence. It reminds me of some old space opera novels from the 50's
which isn't all bad...
