It’s a complex and wicked plot — but apparently none of it was featured in the original version of Cory Finley’s script.
Following a brutal incident involving a horse, Amanda has become a total outcast, but reconnects with Lily when her mother arranges tutoring sessions.
Anya Taylor-Joy and Olivia Cooke play Lily and Amanda in Thoroughbreds — two teens from wealthy families living in Connecticut who used to be friends but grew apart as they got older.
It’s a strange reunion, particularly because Amanda has recently become in-touch with the fact that she has no emotions, but they are able to bond through their hatred of Mark (Paul Sparks), Lily’s emotionally abusive step-father… and before long begin hatching a plan to kill him.
