A Netflix science fiction in which a crew of three is on a two year mission to Mars.
Having just left earth, the crew discovers that a fourth person is accidentally on board. Other problems occur. A CO filter is broken which will eventually poison the crew. Different options are tried to work around the problem, but (of course) it comes to it that there is not enough air for the whole trip for the new size of the crew.
An unlikely attempt is made to get extra air, but this air-walk goes wrong, which brings extra tension to teh film.
“Stowaway” is an alright film with an odd, sudden end.
