A new trailer for gritty British prison drama Starred Up has been unleashed online, and it's every bit as bruising as you'd imagine.
Directed by David Mackenzie ( Young Adam ), the film follows Eric (rising Brit star Jack O'Connell), who's banged up in an adult prison where his volatile temper sees him making no end of enemies.
Oh, and his dad's also in there with him, played by Animal Kingdom stand-out Ben Mendelsohn. "You have to behave," warns Mendelsohn, "'cos they will kill you."
Nothing like a little fatherly advice.

As well as the trailer, a new quad poster for the film has been released. Click below for a high-res version.
Starred Up opens in UK cinemas on 21 March 2014.
