Squibb, who did most of her own stunts in the film, plays a feisty 93 year old grandmother who gets conned by a phone scammer pretending to be her grandson (Fred Hechinger) and sets out on a treacherous quest across Los Angeles, accompanied by her ageing friend (Roundtree) and his motorised scooter, to reclaim what was taken from her.

With infectious humour, Squibb portrays the strong-willed Thelma with grit and determination, demonstrating that she is more than capable of taking care of business - despite what her daughter (Parker Posey), son-in-law (Clark Gregg) or grandson might believe.

"The fact that the film gives June Squibb – the type of actor most people know as scene-stealing characters rather than by name – her first leading film role at the age of 94 is reason enough to see it." The Guardian
