It's difficult to top rats when crafting a horror film, really. A young boy with a vivid imagination, “Danny” (Lee Montgomery), is something of a solitary figure who befriends a rat he calls "Ben." He shares stories about his new companion with his sister, but “Eve” (Meredith Baxter) simply dismisses it as make-believe. Then strange occurrences begin in their community, and whispers circulate regarding a large group of rats causing trouble and attacking people. When vandals—in this case, the rodents—destroy a local grocery store, the police become involved, and “Kirkland” (Joseph Campanella) attempts to understand events that don't quite make sense. His investigation turns up nothing concrete, and even when one of the boys who teases “Lee” is supposedly attacked, it doesn’t clarify anything. Despite thorough searches of underground pipes, sewers, and drains, there’s no sign of them! How will officials uncover the truth? The performances and the script are rather ordinary, admittedly, but the visuals of rats swarming and moving everywhere, combined with the notion that one might be directing their actions, is genuinely unsettling. It's like a legion of ants—only larger, furrier, and possessing more prominent teeth! The film loses momentum somewhat toward its conclusion; however, for a time, the dynamic cinematography and the suspenseful music establish an uneasy feeling that could prompt you to look under your bed and secure your windows before retiring for the night. The Michael Jackson theme song received an Academy Award nomination, it was produced by Bing Crosby Productions, and it’s not as terrible as I first thought.
