Her best friend Andie (Monaghan), single and adrift, gets pregnant from a one-night stand and offers to give Lizzie the baby. Reluctantly, Peter agrees to be the child's father, and before he knows it Andie has moved into the guest room for the duration of her pregnancy. When Peter also invites his ne'er-do-well recovering-addict brother (Weston) to the house, hilarious chaos ensues, testing the limits of friendship, family and a marriage.
