Still reeling from her husband's unexpected death, Kyle Pratt (Jodie Foster) is on a plane heading from Berlin to New York when her daughter vanishes. But the captain (Sean Bean) and the air marshal (Peter Sarsgaard) begin to doubt that the child was ever on board. With no support from the plane's staff, Kyle can only rely on herself to find her little girl. But their growing suspicions about her sanity prove problematic.
