On a stormy night, Laura (
Melissa Gilbert) and Mary (
Melissa Sue Anderson) are held captive at the blind school by three escaped convicts. Since one of the men is wounded, Laura is permitted to go to town to get a doctor -- with the warning that Mary will suffer should she alert the authorities. Even so, Laura returns to the school with her father, Charles (
Michael Landon) -- not a doctor, but just what the doctor ordered to resolve this terrifying situation. ~ Hal Erickson, All Movie Guide
