THE THIRD ALARM (1922)

Because Dan McDowell is unable to operate the new mechanized fire equipment, he is retired with a small pension; his son, Johnny, quits school to work in the fire department; and his old horse, Bullet, is sold to a dirt-hauler. Dan is charged with stealing Bullet and is jailed, but he is cleared in time to give valuable aid in a fire that traps Johnny's sweetheart, June Rutherford.
