When Maria’s estranged brother Nico (Blake DeLong) and his older girlfriend Sigrid (Welker White) show up to help sort out the estate, tensions soon rise about how to best sell the decrepit house. While Maria and Sigrid forge an unexpected friendship, Nico’s emotional state becomes increasingly volatile.
