Thelma Harper and her spinster sister Fran open their home to Thelma's recently divorced son Vinton and his teenage son and daughter. It's quite an adjustment for everyone, especially the cranky, argumentative Thelma.

In this tense psychological drama, an emotionally unstable young woman and her brother drift from town to town. When a sympathetic motel maid takes pity on the girl -- and becomes romantically involved with her brother -- it could inadvertently spell doom for all of them.
