In this sobering indie blend of "28 Days Later..." and "Lord of the Flies" from Ireland, an apocalyptic plague has killed off the adult population, leaving teens and children to fend for themselves in a blighted landscape. A pair of young sisters (Catherine Wrigglesworth, Emily Forster) has only each other for safety and semblance of the past, and that might not be nearly enough. Adam Tyrrell, Jennifer Graham co-star. 106 min. Widescreen; Soundtrack: English Dolby Digital stereo.
