Travis Pastrana does a chute-less jump from an airplane; Andy Bell performs a big wheel back flip.

Parks Bonifay and Mat Hoffman join the cast at Pastrana's Texas lakefront getaway; hydroplaning a motorcycle; drifting prestige cars; dangling from helicopter skids.

For the Nitro Circus crew there is zero down time in Sin City. When they're not launching motorcycles 100-feet plus in the desert or heaving themselves off a 52-story casino on the Strip, they're thinking of other ways to wreak some good old fashion havoc. And it's not just their own lives they're gambling with; the cast goes big with T.J. Lavin and brings Bam Margera to tears.

Creating new stunts and sports; racing big wheels downhill; launching pit bikes off trampolines; monster truck back flip.

The crew uses Utah's rugged terrain to ride, race and wreck everything they can.

Ronnie Renner invites the crew to his California ranch; Johnny Knoxville plays bull croquet; Rob Dyrdek.
