A half-baked 'Terminator' rip-off, with Brigitte Nielsen as an alien sent to Earth to retrieve a crystal before the Bad Guy (Richard Moll. Of course it would be Richard Moll) gets to it.
She teams up with a dull Indiana Jones-wannabe, who has just discovered the crystal, but who is on the run from the local gang boss.
It is actually quite fun, as opposed to many miserably dull cash-ins. There's some quite decent miniature work at the start, although the majority of the movie is on Earth and in more prosaic locations.
