Season 1

When a large amount of money is stolen from a casino vault in the remote desert town of Push, Nevada, IRS agent Jim Prufrock gets a tip that the theft could be embezzlement, so he goes to investigate. He's not made to feel welcome, however, as he is told either to get out of town or ""take careful steps,"" and a meeting with the casino manager ends with threats.

The murder in Push sends Jim looking for clues to the killer's identity, but his efforts are hindered by the town sheriff and his dimwitted deputy, who insist the death was a suicide, although a reclusive tattoo artist may hold a clue to who commited the crime. Meanwhile, a team of well-dressed men claiming to be from the Nevada Gaming Commission arrives to deal with the consequences of the death, and Mary moves to retrieve the stolen loot.

Jim agrees to get a tattoo to get a tip on the killer, and his continuing investigation into the murder reveals some startling facts about the residents of Push but draws the unwanted attention of some well-dressed men purporting to be from the Nevada Gaming Commission. Meanwhile, a funeral attracts an eclectic group of mourners.

With the increase in dead bodies around town, Sheriff Gaines and Deputy Dawn arrest Jim as a possible serial killer. Or is it just a trumped-up charge to keep him from investigating further?

Jim learns what Deputy Dawn is really up to, Grace gets closer to finding out who posted the hefty bail money for Jim's release, and Sloman gives Mary an ultimatum.

With Deputy Dawn's plan unfolding, a desperate Jim risks his life to warn the outside world about Push, and he gets closer to learning the real identities of the well-dressed mystery men.

In the series finale, Jim heads back to Carson City, but has lingering doubts as to whether the mystery of Push has really been solved.
