Son of a gun (HDRip)

Jailed for a relatively minor offense, cocky Aussie JR (19) dares to stand up to the brutish prison gang that sexually abuses his fear-struck cellmate. Thus brave JR, whose chess talent suggests intelligence, is remarked by nationally reputed crime lord Brendan Lynch, who offers them his own goons' protection. Thus effectively enlisted, JR must await orders to help engineer Brendan's daring escape, as turns out by JR-hijacked helicopter. Then he may/must partake in the daring but poorly-planned robbery of a rich gold mine, which proves hard and dangerous, especially as their 'mastermind accomplice' Dave and his nightclub-based gang play a double game. A dubious 'party girl' complicates matters further.
