Dead and Breakfast (2004)

Six friends on their way to a wedding in Galveston stop for the night at a quaint bed and breakfast in the sleepy town of Lovelock. But after a night that ends with both the inn's owner and his chef dead, the gang finds themselves under suspicion by the local sheriff. The mystery quickly unravels when the already bizarre residents of the town become possessed by an evil spirit and pin the friends down at the b&b. Armed with a rusty old chainsaw, a can of gasoline, and a half box of shotgun shells, it's time to barricade the house and fight for their lives.
