A married couple, Bob MacAvoy and Jane MacAvoy, and their young son Steve MacAvoy move to California to start a small newspaper, the Eden Archive. They discover the paper’s offices are worn and in need of care, but they press on with a hopeful plan to build a community paper from the ground up.
Jane soon goes into labor and delivers a daughter in the upstairs of the Eden Archive, a moment that seals the family’s new start in a town that will be watching closely. To kickstart readership, Jane suggests a lighthearted gimmick: print baby photos of local townspeople and let readers guess who’s who. The guessing game quickly catches on and propels the paper into a local sensation, transforming the Eden Archive into a bustling focal point of town life.
However, trouble looms when a photo featuring a mansion front page reveals a building that is actually a prostitution house run by an elderly woman, Mrs. Holmes. The shocking discovery stirs up anger in the community and leads to a sharp decline in subscriptions, threatening the paper’s future.
While Jane canvasses local businesses to place ads, she crosses paths with Myron Trout, the owner of a clothing store who makes advances toward her. She rejects him, but the tension adds another hurdle for the couple as they try to win broader town support.
To attract more supporters, the MacAvoys immerse themselves in local clubs and run a drawing offering a new car as a subscription incentive. A months-long drought grips Eden, and Bob, drawing on his Air Force past, plans to use dry ice and artificially created cumulus clouds to induce rain. The town is thrilled when it seems to rain, but Jane reports in the newspaper that Bob’s stunt somehow brought the rain, and the event quickly spirals into a disaster. The rainfall lasts for days, flooding streets and causing widespread blame directed at Bob.
Pressure from [Myron Trout] and other opponents mounts, and there’s a push to remove the MacAvoys from town. The town’s leaders call for compensation for the rain damage, and a skeptical mood spreads as the couple ponders leaving for New York City, where Bob formerly had a job. Just when it seems the Eden Archive might collapse, a meteorologist Jane had contacted explains that Bob did not cause the rain after all, shifting the town’s stance and renewing hope for the paper’s future. The MacAvoys decide to stay and invest in better equipment, purchasing a new press to keep the Eden Archive alive.
Ultimately, the film’s title It Happens Every Thursday refers to a running joke that the printing press breaks down on Thursday, the day set for printing, a quirk that threads through the story as a symbol of resilience and stubborn, small-town machinery that can still turn a community’s life toward hope.
