Grizzly Park (2008)

A group of twenty somethings doing community service in an experimental program are sentenced to pick up trash at a state park.  On the other side of town, an escaped killer murders the officer driving the Department of Corrections van that is supposed to pick them up.  Oddly enough, the killer puts on the driver's clothes, picks up the group of young folks and drives them to the park.  Even more amazing, he then remains in character to bring all their supplies up to the mountain cabin.

The group is planing to be in the park for one week while the park is closed for the season.  They will be camping and their only supervision is a ranger.  Uhhhhh, that doesn't seem good.  Oh, and one of the guy's brought a bear suit to fool the ranger and pull pranks on the others.  Yeah, that ought to go really well.

The group bonds over stories of how they got sentenced to community service which makes us hate them even more than we already did.  The stories of huffing and prostitution pale in comparison to the tales of killing old people in a nursing home, poisoning your mother, or violently sexually assaulting a fifteen year old and putting her into a coma.  None has any regret for the crimes they've committed, and the ones who did the most heinous crimes are psyched that they were only convicted of misdemeanors.  Oh yeah, can't wait for the grizzly to take care of these jerks.
