From what I gather, Martha Plimpton met River Phoenix through Joaquin Phoenix and/or Corey Feldman, who had both acted
with these two. They acted together twice, first in the movie
The Mosquito Coast, then two years later in
Running On Empty. Martha then accompanied River to the academy awards and they dated for quite some time. It is said that they broke up because
of Martha's anti-drug stance, but it is also said that River admitted before he died that Martha was his soul mate.
