Army sergeant John Payne is ordered to clear up the situation in Laramie single-handedly. He finds his childhood buddy Dan Duryea running a saloon and paying off everyone in sight to keep the work moving as slow as possible; the longer it takes, the more of the rail workers' pay he can pocket. Payne gets himself appointed marshal and jails all the baddies.... but their friends on the juries keep setting them free.
It's another of the 'Shaky A' westerns from Universal in this period, directed by the reliable Jesse Hibbs. Like most of the westerns from Universal in this period, it's in Technicolor, has a couple of minor stars, a few key character actors like Barton Maclane and Lee van Cleef and a spectacular finale of a fight in a train that's about to crash into a passenger train. The result is good, if standard fun.
It's produced by Ted Richmond. He began producing B movies for Columbia in 1940. When Cohn shut down his series, he switched to Universal, where he worked on all sorts of programmers. He produced 56 movies by 1957, and then slowed down. Over the next 22 years, he produced 10 movies, including PAPILLON. He died in 2013 at the age of 103.
