In this stunning and provocative domestic drama about a sweet sixteen birthday party that goes horribly awry, a wealthy family in San Francisco finds themselves entangled in a legal battle, their darkest secrets revealed, and their friends turned to enemies. One invitation. A lifetime of regrets. Sweet sixteen. It's an exciting coming of age, a milestone, and a rite of passage. Jeff and Kim Sanders plan on throwing a party for their daughter, Hannah--a sweet girl with good grades and nice friends. Rather than an extravagant, indulgent affair, they invite four girls over for pizza, cake, movies, and a sleepover. What could possibly go wrong? But things do go wrong, horrifically so. After a tragic accident occurs, Jeff and Kim's picture perfect life in a wealthy San Francisco suburb suddenly begins to unravel. A lawsuit is filed that irrevocably changes their relationship, reveals dark secrets in the Sanders' marriage, and exposes the truth about their perfect daughter, Hannah.
