Lars only leaves the garage where he lives when his older brother Gus and loving sister-in-law Karin drag him to their house next door for dinner. Lars doesn't take well to questioning, so the disturbing level of his isolation is never openly discussed. It's only when he announces he has a girlfriend in the form of an anatomically correct doll he purchased via the internet that everyone must admit his precarious mental state. No one quite knows how to help Lars, so they play along, careful not to do anything that might push him or Bianca (his plastic fiancée) over the edge. The results are touching efforts on the part of all those who love him to help Lars through what his psychologist assures them may be only a stage. Kelli Garner shines as Margo, the real, live girl who Lars seems incapable of seeing. Despite being ignored, Margo hangs in there, hopeful Lars will come around to sanity and to her.
