Evil (2005)

aka To Kako

Three men working construction discover a massive hidden cave and are attacked by something inside it. Each man goes ahead with his plans for the night - one at a club, one at home, and one at the soccer stadium . But none can remember how they got out of the cave or what happened inside. Shortly after conveying this to whoever they are with, each transforms into a zombie and begins biting those around them. Those who are bitten immediately attack others and the town is soon overrun by zombies.

A few survivors meet as they are trying to find safety. They decide to head out of the city in the hope that there are more survivors and less zombies in the countryside. But as happens in most zombie films, things do not go as planned and some inexplicable things happen.

There are some really nice special effects, such as heads splitting in half and an arm being ripped apart. The film was made in Greece.
