Witness

When a young Amish boy (Lukas Haas) witnesses a murder in a big city train station, detective Jon Book (Harrison Ford) is given the job of protecting him.

Suspecting that the murder was part of a police conspiracy, Book retreats to the small farming community where the boy lives.

As time passes, and despite massive cultural difference, the detective falls in love with the boy's widowed mother (Kelly McGillis). 'Witness', the first Hollywood film from Australian director Peter Weir, was nominated for eight Oscars and won two (editing and original screenplay).
