If an inexplicable feeling of dread overcomes you . . . don't ignore it. The residents of this small coastal town do and regret it when a freak tsunami traps a group of them inside a supermarket, where they soon find they are not alone. Their only company, besides each other, is a pack of hungry killer sharks. Starring Alex Russel (Chronicle, Wasted on the Young), Xavier Samuel (Anonymous, Twighlight: Eclipse), Phoebe Tonkin (TV's The Secret Circle), and Julian McMahon (TV's Nip/Tuck, Red).
