Nicky and Tacy are going to be married. Nicky wants to save up money for a house, but Tacy dreams of starting off with their own home on wheels--a trailer. After the two are hitched, they hitch up their trailer and begin their honeymoon. The humor comes from several disastrous adventures the couple has while traveling including Tacy's awkward attempt to cook dinner in a moving trailer, and a cliffhanging ride through the mountains that nearly destroys their marriage.—Daniel Bubbeo <dbubbeo@cmp.com>

Before they were married, Tacy Collini convinced her now husband Nicky Collini to purchase a trailer in which to live so that they could be together as he traveled from job to job working on major infrastructure projects, in the process saving money both on rent and on hotel rooms. They could tow the trailer for their honeymoon across the American west to end up eventually in Colorado where Nicky has his next job. The problems start as soon as they reach the showroom floor to purchase the model they were planning, that issue which may be a harbinger of things to come in both their inexperience in anything associated with trailer life, and their differing viewpoints of their life together in a trailer. The question then becomes if their marriage can survive the multitude of problems that arise, all in one one way or another associated with the long, long trailer.—Huggo

Nicholas 'Nicky' Collini (Desi Arnez) lands a new civil engineering job which will require travel. His fiancee Tacy (Lucille Ball) comes up with the idea of buying a trailer so that they can travel together around the USA to his various work projects, as well as to save money that would otherwise be spent on a house. They intend to haul the trailer themselves to Nicky's first job site in Colorado, as part of their honeymoon trip through the Sierra Nevada mountains. Nicky isn't so keen on the idea of buying a trailer, but he does so. The honeymoon trip, as well as events leading up to it, rapidly becomes a series of disasters.

Shortly after arriving at a trailer show, Tacy and Nicky see a very VERY large trailer home, with which Tacy instantly falls in love, and pressures Nicky to buy. Against his better judgment, as the expensive trailer is over their budget, Nicky gives in. Then they learn that to tow the trailer, the Collinis will have to buy a new powerful car: a 1953 Mercury Monterey convertible, and a trailer hitch, and the expenses continue to rise. Nicky gifts the trailer to Tacy as a wedding present. Driving the convertible towing a huge trailer is a big challenge, and early in the trip the Collinis are jeered at by others on the road.

The first night, their wedding night, the Collinis were swamped by friendly but overbearing trailer park neighbors who take over their trailer and finally leave after giving Tacy a sleeping pill. Tacy wakes up the next day and decides they should leave the trailer park, and instead camp in the woods. However, after they turn onto an old logging road during a rainstorm, the trailer gets stuck in the mud, and it lists dramatically. Nicky tries to level it, which leads to more problems, leading to him falling down into the mud.

The next day, after spending more money to free the trailer and clean it up, the Collinis visit Tacy's relatives. Upon arriving at her aunt and uncle's house, a large crowd gathers to greet them, and they watch as the hapless Nicky, guided by Tacy, backs the trailer into their hosts' driveway and car port, effectively destroying it as well as a prized rose bush. As they're about to leave, they're handed an envelope containing a wedding present check, and Tacy is upset with Nicky when he declines it because of the damage they've done.

As Tacy and Nicky continue their travels, Tacy tries to make the trailer into a home, and collects dozens of mason jars full of fruits and vegetables, as well as huge rocks to decorate their patio when they arrive at their ultimate destination in Colorado. Tacy decides that she wants to drive, but after Nicky criticizes her for fast and reckless driving, Tacy furiously jumps in the back seat and gives him the silent treatment. The fight continues that evening as neither one wants to sleep with the other in the bedroom, and they squabble about who will sleep on the couch.

The next day, they make up. That afternoon, Tacy decides to cook dinner in the trailer while Nicky drives the car, hoping to have dinner ready once he parks for the night. As Nicky happily sings and drives, everything goes awry back in the trailer. As it swerves and wobbles, possessions fly, dinner is ruined, and Tacy, who had been cooking in an elegant dress, ends up in a big mess. After that disaster, Nicky decides to accept an offer on the trailer, hoping he and Tacy could move into an actual house. But Tacy is determined to keep the trailer, and refuses to sell it.

That evening, Nicky orders Tacy to get rid of all the large rocks and jars she has collected before they make a cliff-hanging drive on a narrow road through mountains that will rise to 8,000 feet above sea level. But Tacy, reluctant to throw away what she considers precious memories of their honeymoon, decides to hide the items so that Nicky won't find them. As they undertake the harrowing mountain drive, everything Tacy has hidden rolls around inside the trailer, making a big mess.

Finally, when they reach the top of the 8,000 foot mountain, the trailer, weighed down by all of the possessions, gets stuck and its wheels spin. Nicky discovers the rocks and jars, and in a rage, he takes everything Tacy has collected and throws it off the mountaintop. Tacy later storms off in a huff.

Some time later, as their marriage deteriorates, Nicky meets up with Tacy as she prepares to sell the trailer and move back home. Nicky wants to apologize, but doesn't know where to start, and Nicky leaves. As he drives away in the pouring rain, Tacy runs to catch up with him. The two finally forgive each other, and tearfully reconcile.
