Synopsis

Dank einer Idee, die Brian im NZT-Rausch hat, züchtet der Genetiker Arthur Maciel eine unsterbliche Maus. Nachdem er seine Entdeckung bekannt gegeben hat, wird das Tier jedoch gestohlen – möglicherweise von Maciels ehemaligem Geschäftspartner und jetzt größtem Rivalen Paul Wilkerman. Kurz darauf wird dieser ermordet aufgefunden, und überall am Tatort sind Maciels Fingerabdrücke. Verzweifelt bittet der Gen-Forscher Brian um Hilfe.
