Fierce People (2007)

When 16-year-old Finn is caught buying cocaine for his junkie but well intentioned mother Liz, his plans of spending the summer away from NYC with his anthropologist father studying the Ishkanani in the jungle are abruptly changed. In an attempt to get both of their lives back on track, Liz moves the two of them out to a cottage on the country estate of her sugar daddy, Mr. Osborne. Finn immediately makes his way into the 'tribe' of wealthy country clubbers that inhabit his new home. Soon Finn is dating Mr. Osborne's granddaughter Maya and has found a best friend in her brother Bryce. Finn adjusts quickly to their life of fancy clothes, cars, horses, sex and drugs. Liz begins attending AA meetings and begins to establish herself as a loving mother working to correct her mistakes and win back Finn's love and trust. Unfortunately things begin to spiral out of control, and he begins to see that the wealth and friendships bestowed upon him come at a price.
