College dean Higgins (Joe Flynn) is trying to cut the chemistry department budget. He dismisses all the science being done by the students. A lightning strike hits the lab. The next day, Dexter Riley (Kurt Russell) checks the damaged experiments and discovers an invisibility liquid. He shows his friends Richard Schuyler and Debbie Dawson. Crooked investor A.J. Arno (Cesar Romero) has bought up the college's mortgage. The Dean is clueless but the three friends suspect Arno has nefarious motives.
This is the second of the Dexter Riley movies from Disney. It is charming family fun. There is an endearing innocence about these movies. Baby-faced Kurt Russell is great. I also love the pre-CGI special effects. As a kid, I was engrossed by them. As an adult, I am enchanted by them. The story is silly but that's also part of the charm.
