i need help identifying a movie. there was a woman in a safe house in the woods somewhere she was being protected in order to testify in court. the house gets attacked by nefarious individuals who may be with fbi or cia. she escapes and gets a ride to the local police on a lumber truck. when she gets there the police call to check her story but the call gets intercepted by the agents who are trying to kill her and they go to the police to get her and the police station gets all shot. these details may be off in spots but the ride on the lumber truck is prominent in memory. i don't know the year released. if some one could provide a cast member i could track it down that way. thanks
