This movie scared the shit out of me back when I saw it in the 80s.

[quote]In an ultra secret laboratory for the developing of biological weapons, covered as "Biotek", a research center for agriculture, a serious accident occurs, spreading a sinister bacteria in the laboratory. The security guard of the complex, closes and seals the building, with all the personnel inside, making very difficult the struggle for survival, not to mention the actions that the relatives of the enclosed people are thinking to do.[/quote]
