Wonderland follows three generations of one family as their separate paths cross each other. Debbie (Shirley Henderson), Nadia (Gina Mckee) and Molly (Molly Parker) are three sisters. Molly is due to have her first baby any day. Debbie has a nine-year old boy, Jack, but still wants to spend her nights on the town. Nadia lives alone and is looking for someone to fall in love with. Their quest is familiar and eternal: how to find some contentment in this world.
