chunk: Kate Hannah (Mary Elizabeth Winstead), an elementary school teacher, arrives at work hungover and vomits in front of her class. Asked by a student if she is pregnant, she pretends she is, then continues the lie to the school principal, Mrs. Barnes (Megan Mullally). Her co-worker Dave (Nick Offerman) reveals that he knows she has been drinking and she makes him swear not to tell anyone.
  Attending a party with her husband Charlie (Aaron Paul) and his brother Owen (Kyle Gallner), Kate drinks heavily. While leaving, she meets a woman who asks Kate for a ride. Kate is offered crack and the two get high together. The next morning, Kate wakes alone on the street. She finds her car and drives home, where Charlie acknowledges they both are alcoholics. They get intoxicated and have sex before Charlie passes out. Kate heads out alone to buy wine but is turned down by the cashier. She urinates on the floor because the bathroom door is locked, then steals a bottle of wine.
