Jason Robards is obsessed with transcendental meditation and is constantly trying to get his wife to experiment with him. They live in a classic turn of the century style house near the school - so near in fact that he keeps threatening the school kids who keep cutting through his garden - notably Corey Feldman and Corey Haim. Just as he finally cajoles his wife one night into experimenting with the meditations with him out in the garden, Feldman and his girlfriend, or rather the girl he would like to be his girlfriend, ride through on their bikes colliding with the couple and with metaphysics.
Several improvements are made on the classic "Freaky Friday" theme. For thing, Feldman and Robards are adversaries. For another, it is not just Robards and Feldman that make the switch. His wife has too but she doesn't realize it. She, as Feldman's young girlfriend, doesn't understand why she can't remember her locker combination or dance routines. As Robards, with help from Haim's character, tries to adjust to life as a high schooler in the days of mousse and Michael Jackson, he is haunted by cryptic dreams where Feldman - who seems to know more than he is letting on - warns him that he must make her realize who she is before it is too late and Robard's wife is lost forever.
