Set somewhere in New England, the plot of this murder mystery involves the death of the patriarch of the Thrombey family, Harlan (Christopher Plummer). Harlan is a wildly successful mystery novelist who has amassed a small fortune running a publishing company for his and other books. While initially thought to be suicide, several guests at Harlan's 85th birthday acted quite suspiciously before his death that leaves open the possibility of foul play. Along with the police, an unknown person hires a famous detective named Benoit Blanc (Daniel Craig) to check into the matter beyond the standard police questioning. Our main conduit into the story, however, is Marta (Ana de Armas), Harlan's nurse that has a strange affliction where she will toss her cookies whenever she lies, making her an instant way to vet the truth, provided that she knows it. With Marta by his side, Blanc finds there may be more to the suicide than he initially thought, though the hows and whys remain elusive. Rian Johnson writes and directs. Chris Evans, Don Johnson, Jamie Lee Curtis, Toni Collette, Michael Shannon, and LaKeith Stanfield also appear.
