It's winter in the Bavarian village of Leavenworth, Washington, which for local brewmaster Sloan Krause means lots of layers, pine and citrus-flavored craft beers, and getting the new guest rooms at Nitro into pristine condition before visitors flood in for IceFest-a local tradition filled with fireworks, ice carving, and winter games of all varieties. But Sloan and her boss Garrett quickly learn that being brewkeepers turned innkeepers may not be as idyllic as it sounded.
While one couple staying with them seems completely smitten, a flashy group arrives in the evening demanding rooms. Sloan and Garrett are less than impressed, but agree to rent to them anyway. The night takes a turn when brewery patron Liv Paxton finishes her frothy pint and, with no previous plan for an overnight stay in Leavenworth, eagerly takes Sloan up on the offer of sanctuary from the snow-until she has a strange run in with some locals and the other guests. Sloan could be imagining things, but when Liv's room is found trashed the next morning, a hateful message painted on her car, and Liv herself is nowhere to be found, Sloan is convinced another mystery is brewing. With many of the potential suspects hunkering down under Nitro's roof, she knows her co-workers and friends won't be safe until she serves up the killer a hoppy pint of justice.
