An alcoholic film editor puts together the pieces of his movie star sister's murder.

Cass juggles jobs as a nanny, restaurant server, and party drug dealer in order to make ends meet and pay for their tiny San Francisco apartment. After a one night stand with Kalli, a co-worker they have a crush on, Cass agrees to watch her 11-year-old daughter, Ari, while she goes out of town. But as days pass without word from Kalli, Cass and Ari form a bond that spirals Cass back to their own difficult childhood and the pain they’ve been running from.
