The movie is absurd. Billed as grandmother and grandson bonding against his parents/her daughter & husband, who treat them as infants, there is relatively little of that. Most of the movie involves 93-year old Thelma and her fried Ben driving across LA on a scooter to get revenge on a crook who scammed her out of $10,000. Ben initially tries to stop her, but after she steals his scooter, smashes someone else's scooter and steals a gun from a 3rd person, Ben changes his mind. Why? Why not just go to the police? The suggested premise sounded interesting but none of this movie makes any sense.
