Saw

A horror thriller with enough blood and gore to satisfy aficionados of this genre. Two men find themselves chained up in a raunchy underground bathroom with a dead body in a pool of blood between them. They have no idea how they got there. The only things they have are a tape from the maniac who put them there and a saw which will not cut their chains but will serve to cut off a limb if they really really want to free themselves. The trailers for this film were very good.
