Dwayne "The Rock" Johnson helps conduct a prison boot camp with prisoners in his new HBO documentary Rock and a Hard Place, whose trailer was released today. The clip shows the actor speaking with young felons at a Miami facility where he explains that he was once like them when he was their age.

38 male criminals will take part in the boot camp program for four months, which the trailer points out is an alternative to 20 years in prison. "Don't f-ck this thing up.
