Netscape's engineers spend the last months of the twentieth century racing against a deadline they set themselves: open-source the browser code that built the company, before Microsoft's free bundling of Internet Explorer finishes the job of killing it. The film follows programmers including Jamie Zawinski as they strip proprietary code out of the Netscape browser line by line, arguing over licenses, working through nights, and watching the AOL acquisition close in around them. Cameras sit in cubicles and hallway meetings rather than boardrooms, catching the unglamorous mechanics of a company trying to give away the thing it was built to sell. Zawinski's resignation, filmed as it happens, becomes the clearest measure of what the release costs the people doing it. The Mozilla project that results would eventually seed Firefox, though nobody on screen knows that yet. What the film actually documents is smaller and more immediate: engineers who believe in open code trying to save a company that may already be lost.
