Bajocero

In BELOW ZERO, police officer Martin (Javier Gutierrez) starts his first day in a new precinct. His first assignment pairs him with an aggressive partner, and they must drive a large prisoner transport van with a small number of inmates to another prison. The problem is they must leave during the dead of night, and it's very, very cold outside. There also seems to be someone after the transport van. Are they friend, foe, both, or neither? Who can Martin trust?
