Watch Alien V. Alien

Two alien races have crash-landed on Earth and set out in search of the obelisk that monitors all life on the planet, and now the future fate of mankind lies in the efforts of one benevolent extraterrestrial to deactivate the device before his nemesis reaches it first. Sixty years ago, the Omega race left several ether-rods on the plane before blasting back into outer space. Now it's up to an Omegan named Jude to find those rods and deactivate the obelisk. Should he fail in his mission, malevolent Omega-cinterion Cronin will no doubt activate the device - effectively erasing all traces of mankind. As the race between the two aliens heats up and the threat of ultimate apocalypse grows, mankind remains blissfully unaware just how close to the brink they truly are.
