The whole movie has a kind of grainy quality -- actually it's just really grainy... and the word quality probably shouldn't be associated with it. In a pointlessly surreal style, we are introduced to the "players" in a series of scene cuts, and it is implied that an alien has landed, and is being examined (or evaluated) in some kind of lab.
This is where the females make a point of stating how attractive they find the subject, but this is done in a way that is either creepy, or just really poorly acted - it's hard to tell which. The men on the team seem to indicate that the reaction of the women merits some kind of discipline, which would lead us to believe these beings have been encountered before and these responses lead to bad outcomes, but this is supposed to be the "first" man (alien).
Later we are shown some wreckage on a hillside (everything is around Los Angeles), but there isn't enough of it to have carried a gerbil, much less a man. The agents are tasked with killing people when necessary, and the movie descends into an exploration of their feelings about that, and to pad the movie, their interpersonal relationships were superficially examined.
No scene in the movie seems to get you to the end fast enough, and we know nothing more at the end than we did at the beginning.
