Trip Slip is a comedy film that revolves around three middle-aged friends who have been paying child support for years. The trio, John, Dave, and Joey, are excited that they have finally come to the end of their child support payments. They decide to celebrate the occasion by going on a boys' night out.
However, their wives aren't too thrilled about their husbands' plans, as they think the celebration is unnecessary. The wives remind them that they still have other responsibilities and obligations as fathers, and that not having to pay child support doesn't mean they can shirk their parenting duties.
Despite their wives' objections, John, Dave, and Joey manage to convince them to let them have their night out. They plan to go to Las Vegas and have a wild and crazy time, reliving their youth and getting into all sorts of mischief.
As they journey towards Las Vegas, the men encounter all sorts of mishaps and misadventures. They run into a crazy party girl who almost gets them arrested, a group of bikers who want to beat them up, and end up losing all their money at a casino.
After a night of drunken debauchery, the men wake up hungover and regretful, realizing that their wild night out wasn't worth the trouble they caused. They come back home, facing the consequences of their actions, but also realizing the importance of their role as fathers and husbands.
In the end, the men learn that there are more important things in life than a single night of freedom, and that being responsible fathers and husbands is their primary responsibility.
