Six astronauts/scientists on the International Space Station study samples that have just been successfully collected on Mars. They hope to find out more about the conditions on Mars, but what they find instead is actually life: a single cell organism that’s either dead or dormant – but it’s there. They can barely contain their excitement, especially when their attempts to revive the organism are actually successful. But they have never encountered a live form like this – and it quickly turns out that it’s more than they bargained for.
Life is a decent, albeit derivative film that works pretty well – at least if you don’t keep comparing it with the Alien franchise it is a little sibling of.
