V kazhdom cheloveke est i Bog, i dyavol, no vse zlo, ravno kak i vse dobro v mire, proishodit ot ruk lyudey, ot ih pomyslov i deyaniy. Slovom, ot togo, kakuyu rol dlya sebya oni vybrali - dyavola ili Boga. Kakuyu rol vybral dlya sebya Lev Royzelman, blistatelnyy uchenyy, vsegdashniy konkurent Aleksa Kmotorovicha? Lev predlozhil reshit problemu detorozhdeniya, sozdav spetsialnyy apparat po vynashivaniyu detey. Mnozhestvo semey okazalis blagodarya nemu schastlivy. I ne vazhno, chto kazhdoe vynashivanie oborachivalos dlya zhenschin poterey konechnosti! ZHertvennost - bezuslovnaya cherta vsyakoy materi! Feliksu Zaryanichu i ego druzyam udalos vyyasnit, s chem svyazana geneticheskaya mutatsiya, ohvativshaya ves mir, i ponyat, kakova glavnaya ideya Lva Royzelmana.
