Two sisters who inherit a run-down roadhouse/garage from their Uncle Ted. It is situated in the fictitious locale of Frog's Hollow, located somewhere on the Hume Highway mid-way between Sydney and Melbourne. They also inherit the services of Charlie Appleby, a lazy, decidedly third-rate mechanic played by Eddie Hepple. Stewart Weller played a support role as Stinger, Charlie's best mate and 'partner in crime'.
