Witness

In 1984, an Amish community outside of Lancaster, Pennsylvania attends the funeral of Jacob Lapp, who leaves behind his young wife Rachel and eight-year-old son Samuel. Rachel and Samuel travel by train to visit Rachel's sister, which takes them into Philadelphia. While waiting for a connecting train, Samuel goes into the men's room and witnesses the brutal murder of an undercover police officer, but manages to evade detection by hiding in the stalls.
