***1/2 (three-and-a-half stars)
There is a real concussion at the beginning of the antiseptically beautiful "Concussion," but it's also a metaphor that's no less jarring. When Abby (Robin Weigert), a suburban lesbian married to Kay (Julie Fain Lawrence), gets hit by a baseball thrown by one of their children, it sets off a need for change in her routine existence. She works on renovating a downtown loft with a contractor, Justin (Jonathan Tchaikowsky), who also pimps on the side -- and Abby decides to take female clients as a high-end hooker, using the professional name Eleanor. Writer-director Stacie Passon's sexually charged premise becomes a vehicle for an emotional exploration of a stagnant relationship and the struggle between desire and stability. Weigert (best known for her work on "Deadwood") gives a performance that's revelatory in more ways than one, as Abby sheds inhibitions and clothes. The slick look (by production designer Lisa Myers and art director Kevin P. O'Donnell) highlights the split between Abby's suburban oppression and her urban freedom.
