While most Christian films are low budget and show it, Red Line has great special effects, actors and is quite the thrill ride.  Unlike other Christian films, this movie is not preachy or tacky.  While it does praise virtue, the message it's trying to share is the insecurity of today's subway systems.  Red Line is about a terrorist attack on a subway that blasts apart a train taking many lives in the explosion and impact.  The survivors are left to fend for themselves and doubt each other's intentions when they realize that the bomber is among them.    I'd say more, but I don't want to spoil anything.  This is a movie you have to experience for yourself.
