Things aren’t going well for Mags and Ash, an L.A. couple who are each busy struggling with their businesses — she’s forced to be a fund manager with her dismissive dad; he’s trying to juggle investors on the way to his own imported pot seed operation. They’re doing well enough to have a nanny for their one child, and getting ready to take their first trip as a couple alone since becoming parents. 

Things are sunny and fun in the Mexico resort they visit, where Mags finds a strange attraction to her exotic yoga teacher; Ash encourages this connection, thinking it will result in a threesome he’s a little too giddy about.  Things don’t progress as smoothly as they all want, but that only adds a realistic tone to the comedy.

“You Me & Her” was written by its star Selina Ringel, who finds a nice showcase for her talents, much as she did in her 2021 film “Single Mother by Choice,” a pandemic-era film that she filmed using her own pregnancy. She writes her character as pretty close to the truth – a half-Jewish Mexican-American from Guadalajara and allows her sunny, sometimes unsure personality through. 

Once again she’s working with her husband Dan Levy Dagerman as director, who knows keeps things sharp. Playing her husband in the film is Ritesh Rajan, who has popped up in episodes of “Russian Doll” and “Stitchers.” He brings a little complexity to his character, who tries to come off as easy-going, but is hiding a potentially disastrous financial deal, and is a little anxious about how the potential tryst will play out. 

As the free-spirited yoga teacher the couple has their eyes on, Sydney Park (of “Pretty Little Liars: The Perfectionists” and “The Walking Dead”) retains a kind of mystery and allure as she guards her intent and keeps them guessing. 

The couple first tests themselves when they run into a swinging couple that are a little too goofily forward than they’re comfortable with. And the film adds a little more conventional humor when a couple of neighbors come over to investigate what is happening. 

Nothing outsized happens — no cops ever show up; there’s no explosions — but that keeps in keeping events believable and human-sized. 

“You Me & Her” isn’t a big movie, but it’s an amusing enough one that seems fresh and contemporary to boot.
