They come to this alien planet (not Alien alien, just extraterrestrial) and decide to land immediately without any surveillance from the orbit. Luckily out of the whole planet the place they happened to fly over had alien structures so they land there. Only then the scientists learn from the mission director what they are allowed to do. They go to this alien structure with their hi-tech equipment and an android. The android presses all the buttons he can find like 5 year old and nobody's surprised that he doesn't explain anything. Apparently he mastered a couple of ancient earth languages but that's no explanation to why he understands alien writings. The guy operating the hi-tech probes that map the structure suddenly flips out when he sees an alien corpse while everyone else is cool, decides to go back to the ship and gets lost in the tunnels. In the structure they decide that the air is breathable on the basis of it's chemical composition and take off their helmets. Who in their right mind exposes oneself to an alien environment. You don't know what can be in this air especially that you're looking for alien life. Then out of nowhere a sand storm appears as if triggered by their actions. So they retreat and they take the alien head with them to the ship while the geo-expert most competent on finding his way back gets lost in the structure. In the ship they do decontamination of the alien head but they fail to decontaminate their own heads after the exposure to the alien environment. And now the best happens: The paleontologist/archaeologist suddenly becomes an expert on alien physiology and just by looking at the head decides that there are some new cell outgrowths on the forehead. They decide to reanimate a 2000(?) year old head by using electroshocks after which the head explodes. (What was the point of that scene? To show their incompetence?) Then they examine the alien DNA under the microscope(!) and the analysis tells them it matches human DNA. (Wow really? After millions of years of evolution of human species it's still the same? Oh wait, you can "choose to believe" so. Yet the opening scene of the alien committing suicide and dispersing in the water with cool particle effects suggests that he initiated all the life on the planet. But then again the ancient cultures worshipped the solar system the alien structures were on. So maybe we are their direct descendants. But it's not where the alien race comes from. It's just a storage place for biological weapon. Why would the aliens leave an "invitation" to their military base?) Meanwhile the android opens one of the vases they found in the structure like he knew exactly what he's doing. All in his room without any secure containment. He brakes open a vial of unidentified liquid which for all he knows could be kryptonite or cool-aid and decides to roofie one of the scientist with it. Meanwhile the guys that were afraid of the alien corpse and got lost in the structure decide to make friends with a snakelike life form that emerged from a puddle and get raped by it. The roofied scientist gets sick but before that he manages to have sex with his colleague (Elizabeth) and impregnate her with an alien life form. Then the android scans the Elizabeth on the next day like he knew what he was looking for and tries to restrain her so she will give birth to an alien. (Why would he want to do that???) She escapes and uses automated surgical chamber to remove the alien from her belly. The procedure cuts through her whole abdomen and then staples it back together. From now on she runs around in all action scenes with her severed abdominal muscles. (The least they could do is show some hi-tech quick healing procedure or something.) She escapes and finds Wayland to be on the ship and he's looking for cure to old age. No one is surprised she has a gushing wound across her abdomen and they embark on another trip to the alien structure which turned out to be a spaceship. They revive one of the alien crew members which goes on a killing rampage after a chat with the android (no explanation why) and decides to fly the spaceship to eradicate life on earth. Fortunately after a quick chat with the female protagonist the pilots enthusiastically decide to go kamikaze on the alien spaceship and die with smiles on their faces. Then there is the nerve wrecking scene of the doughnut spaceship rolling and chasing Elizabeth and Meredith in a straight line when all they had to do to avoid it was to step aside. The alien pilot somehow survives the crash and comes back with a revenge on his mind. It is defeated by the foetus Elizabeth gave birth to which grew to a gigantic size on absolutely nothing in a matter of hours closed in the operation chamber. In the end Elizabeth joins forces with the android who poisoned her lover and tried to kill her as well and they fly off to find the home planet of the alien race.
