Unlikely Angel

Parton stars as a somewhat-selfish country singer, Ruby Diamond, whose untimely death while driving at night results in her gaining an audience with Saint Peter (Roddy McDowall). He offers her a rather unusual arrangement: she will return to Earth on a mission to reunite the suburban Bartilson family (a family that's been torn apart ever since the mother died). If she succeeds by midnight on Christmas eve, then she will be granted her wings as an angel. If not, she will receive a fate much worse.
