Planning to purchase a station wagon, lawyer Dave
Crabtree
is distracted when he becomes fascinated
with a decrepit 1928 Porter. Inspecting it, he hears
a feminine voice call his name. Finding that the voice
emerges from the radio, he discovers that the car is
his mother, the late Abigail Crabtree, reincarnated.
Concealing the fact of reincarnation, Dave struggles
to defend his mother against a family who eagerly
await a station wagon; and, from the devious attempts
of Captain Bernard Mancini, an antique car collector
who is determined to add the Porter to his collection.
