Chameleons (1989)

In this failed television series pilot from the mind of Glen A. Larson, Shelley (Crystal Bernard), a slightly-crazy heiress, discovers that her eccentric millionaire uncle Jason Carr (Stewart Granger) was rather more eccentric than even she had thought. He was a costumed superhero in his spare time, half of a duo calling itself "Captain Chameleon and the Paraclete of Justice". Now Shelley must find out exactly who murdered her uncle, with the help of her uncle's mysterious and handsome partner in fighting crime.
