I've searched the title of a movie I watched long time ago but got no result so far. I do remember part of its story. It's about a girl who is pursued and threatened by certain people after she stumbled upon a catacomb? (an ancient tomb I think). I remember the part that she was actually one of the people who stood there and watched Jesus dying 2000 years ago and she along the other people who just watched him came to be reborn throughout the history to be killed again and again under curse. It was a kind of horror/mystery movie that has an interesting theme. I really want to watch this movie again. Can anyone help me?

The Gathering (2003)
Wikipedia synopsis excerpt:
Cassie Grant (Christina Ricci) is a young girl from the United States who is wandering through England on foot. On her way to Ashby Wake, Cassie is hit by a car. The driver of the car, Mrs Marion Kirkman (Kerry Fox), immediately calls an ambulance. During an examination at the local hospital the doctor comes to the conclusion that Cassie only has some scratches and not even a concussion, but Cassie has lost her memory due to the accident. She only knows her name and mother country, but she does not know which town she comes from, who her family is and why she is in England. The doctor explains to her that the loss of memory is caused by a shock and that she will regain it. As a result of the examination Cassie is checked out. Kirkman invites Cassie to her house until she has overcome her memory loss.
While recovering, Cassie is drawn into a deeper mystery which seems to involve her hosts and other people she sees about the town. Her lack of memory compounds the air of suspense as she encounters a man named Dan Blakely (Ioan Gruffudd) she believes she knows but not from where. Cassie becomes attached to Kirkman's son, Michael (Harry Forrester) and becomes acquainted with her husband, Simon (Stephen Dillane), an art historian who is in the process of examining a church from Early Christianity built in Glastonbury during the first century AD after the arrival of Joseph of Arimathea. This church was recently discovered by two visitors to the Glastonbury Festival who died after falling down a hole through the open roof of the buried church. In the church, there is an unusual relief made of stone that llustrates the crucifixion of Christ. Also depicted are many curious onlookers who appear to be observing the gruesome scene.
