River Dog

Max (Jason Behr), Liz (Shiri Appleby), Michael (Brendan Fehr), Isabel (Katherine Heigl), and Maria (Majandra Delfino) rush to gather as much information as they can from the mysterious geodesic dome in Texas, and are nearly caught in the process. Isabel finds a locket engraved with a strange symbol, which is revealed to be the same image she and Max had drawn in the sand years earlier. Later, they come into contact with a Native American (Ned Romero) who recognizes the symbol and implores them to discard the locket, as it is a harbinger of death. Meanwhile, Ms. Topolski (Julie Benz) is still conducting her manhunt, and Sheriff Valenti (William Sadler) begins to indicate that he is on to her double life.
