Mysterious old solicitor Mr. Blunden visits Mrs. Allen and her young children in their squalid, tiny Camden Town flat and makes her an offer she cannot refuse. The family become the housekeepers to a derelict country mansion in the charge of the solicitors. One day the children meet the spirits of two other children who died in the mansion nearly a hundred years prior. The children prepare a magic potion that allows them to travel backwards in time to the era of the ghost children. Will the children be able to help their new friends and what will happen to them if they do?

The film opens in a happy, comfortable upper middle-class home in Edwardian London. One night in 1905, the three children see their father usher two strangers into his study. After an argument he leaves with them and does not return. They and their mother fall on hard times and eventually move to a cottage in the country. Yet they keep their spirits up and find ways to help others. Fascinated by the nearby railway, they wave to the passengers faithfully every day, and their vigilance and courage prevent an accident. Their kindness makes friends of some important people who can help solve the mystery of their missing father. Written by Paul Emmons pemmons@wcupa.edu
