De komeet Halley is weer eens in de buurt van de aarde en een Engels/Amerikaans team gaat in een space shuttle de komeet onderzoeken. In de komeet Halley blijkt een buitenaards ruimteschip verborgen te zitten. Nadat de space shuttle uit de ruimte terugkeert blijkt er maar een overlevende te zijn namelijk Tom Carlsen. Plotseling komt de rest van de bemanning weer tot leven en begint de ellende.
Nee, helaas is Lifeforce nog niet beschikbaar op Netflix in Nederland.
