Season 6

The Troopers chase a wanted and dangerous man through a forest, clear small villages from illegal bootleggers, help a man under the influence of drugs, and protect the community from a curious bear.

The Troopers bring down a drug trafficking felon and stop illegal hunters from slaying helpless fowl, while Wildlife Troopers investigate the mysterious appearance of several trucks that have torn up a nature preserve in the Mat-Su Valley.

The Troopers battle a crippling forest fire, handle a nail-biting standoff and take on a drug-filled traffic stop. With wilderness conditions out of their hands and a desperate gunman firing at random, Troopers never know how each shift will end.

Illegal moose hunters are on the prowl in the mountains of the Mat-Su Valley and the Troopers set out to hunt them down. The Troopers track down and arrest international felons and detain a drugged up fisherman.

On a dangerously cold winter night, the Troopers hunt for a man who is threatening to end his own mother's life. The Troopers let loose at the 53rd annual shooting competition against the Royal Canadian Mounted Police.

Follow the troopers as they enter into the cold, dark and dangerous world of Alaska's criminals. In the Mat-Su Valley, Sgt. Manrique is forced into a father and son conflict in which the father nearly stabbed his son to death. Then in Wasilla, Trooper Cronin investigates a suspicious truck in a gas station parking lot and finds a familiar face — a felonious woman he's been searching for. Meanwhile up in Fairbanks, Trooper Haley gets word of an intoxicated man camping in the Alaskan woods.

From a hot pursuit on ice-covered roads to a moose disrupting busy streets, no patrol measures up to the bone-chilling magnitude as those of Alaska's state troopers. In Fairbanks, Trooper Rallo is in dangerous pursuit of a stolen vehicle. Down in Palmer, a call comes out to Trooper Taylor of a car accident involving a moose on the Glenn Highway, where thousands of drivers commute every day. In Homer, Trooper Chaffin searches for the suspect of a local burglary before he flees the state.

Troopers Noll, Taylor and Hess arrive on the scene of a crime of sheer brutality. A scorned ex-husband has been viciously stabbed, leaving him nearly eviscerated and on the verge of losing his life. In the Mat-Su Valley, Trooper Determan is called to investigate a rolled-over vehicle. When he and the paramedics arrive, they find the car in a frozen swamp with an unconscious man trapped inside. Then in Juneau, Wildlife Trooper Bjork investigates nearly 100 unattended shrimp pots in the waters.

Trooper Cronin is patrolling Palmer's slippery streets when he gets a call about a suspected drunk driver going in the wrong direction. Across the valley, Trooper Taylor investigates the theft of a $15,000 ATV and goes on a 12-hour hunt that leads him into the Alaska woods in the dead of night. North in Fairbanks, Trooper Mike Munson responds to a call that a man who threatened his former landlord's life is stalking outside the landlord's home.

On the Parks Highway — the busiest stretch of road between Anchorage and Fairbanks — a head-on collision between an SUV and semi-truck shuts down the highway. Trooper Anderson arrives at the scene to find those in the SUV badly injured, and must work quickly with the emergency crew to save those whose lives are on the line. Across the valley, Trooper Noll responds to a burglary in progress and drives head-on into imminent danger, chasing after the suspect on ice-covered roads.
