The Lonedale Operator

D.W. Griffith at his most economically thrilling. A young woman takes over her father's post as telegraph operator at a remote railway station. When bandits arrive to rob the payroll, she barricades herself inside and frantically wires for help. Griffith cross-cuts between the besieged operator, the approaching rescue train, and the criminals trying to break in — building suspense through parallel editing with a precision that was revolutionary in 1911. The final reveal of how she held off the robbers is a delightful twist. In just seventeen minutes, Griffith essentially wrote the grammar of the thriller.
