Fan Casting The Wolf in Everyone

After a successful heist, a quartet of robbers flee but are forced to take a young woman as a hostage. After reaching their hideout, a large abandoned farm in the middle of nature, at nightfall, their boss doesn't care about the few collateral victims caused by the most volatile of the group. He also seems to care little about what they should do with the potential witness, as he really wants to get his hands on the particular loot his men bring back. However, things are starting to go wrong, as at least one person here doesn't want to share and, away from the rest of the world, it seems that this loot is only enough for one person !
