The crew of the International Space Station picks up a delivery with samples from Mars and during their investigation of the contents, find a one-celled life-form.
The life-form proves to be able to grow and in a story with little surprises (except in the last seconds of the film) we follow the ‘Martian’ growing out of control.
“Life” is descently made and clearly shows the dangers of testing with unknown material, but in basis it is a scifi like many have been made.
