Revealing nothing more than the movie trailer, the new film "Stowaway" creates a scenario where an interplanetary scientific expedition to planet Mars is jeopardized by the presence on board of an unknown third party - a "stowaway." Obviously, there is not enough food or oxygen on board to take care of FOUR people when the whole thing was planned for three. The film shows what the four of them do in response to this true dilemma.
But to be vulgar about it, after the dust settles on this expedition, we have two healthy young men, a cute, sexy young woman (played by Anna Kendrick), and an ugly old crone on board, and one of them has to go - one way or another. The whole thing takes place in the first couple weeks of this TWO YEAR expedition.
Is it plausible to posit that the two healthy young men would insist that the Ugly Old Crone be jettisoned?
