Even while on the lam from the Feds, brash bank robber Larry Kulhane (Gerald O'Loughlin) masterminds another major heist. This time, Kulhane's prospective victim is elderly Ardyth Nolan (Jessica Tandy), who has recently come into possession of $200,000. Planning his caper with meticulous care, Kulhane has installed one of his accomplices as Ms. Nolan's butler, and another as the bofriend of the woman's impressionable granddaughter. The final stage of the plan is to murder the feisty but frail old lady--unless Inspector Erskine (Efrem Zimbalist Jr.) can get to Ms. Nolan first.
