A Simple Favor 2018 / Now On Amazon Prime

Anna Kendrick and Blake Lively star in this crime-comedy as two opposite mom personalities: one a stay-at-home food vlogger, and the other an upper-class businesswoman.

Kendrick’s character (Stephanie, the vlogger mom) agrees to pick up her new friend’s kid from school. However, the kid’s mom disappears, leaving Stephanie to lead an investigation on her own into what happened.

This is a funny no-brainer carried by the two leads’ unlikely but genuine chemistry.
