Here’s a synopsis for The Guilt Trip:

Andy Brewster (Seth Rogen) is an inventor who lives in Los Angeles. He’s come up with an amazing organic cleaner but can’t get anyone interested in manufacturing it.

Andy plans a business trip to promote the product and decides to take his recently-widowed mother (Barbra Streisand) along for the ride. She’s been despondent since his father died, so he comes up with a great idea—during the trip he’ll surprise her with a stop in San Francisco, where one of her ex-flames lives.
