The Foundling - S1.E1

When a young girl is left on the doorstep of the Walton's home, they take her in. Not Before learning she is deaf after taking her to the doctor. One night while the Walton family listen to the radio John boy takes matters into his own hands when Holly (the deaf girl) runs up to her room crying. He teaches her sign language...or really Sign spelling! This new skill comes in handy when the youngest of the Walton family gets locked by accident in a box in the Haunted House, which later turns out to be the house of which Holly lives!
