Mimic: Sentinel

Marvin Montrose (Karl Geary) wants to leave his apartment, but he lives sealed inside a plastic bubble, and the only world he gets is the view from his window. J.T. Petty sets the story in the complex across the way, where Marvin's sister Rosy (Alexis Dziena) and their friend Carmen (Rebecca Mader) are left to defend the building from the mutant Judas Breed insects. Brother and sister stay bound through that window, one watching, one holding the door.
