very interesting sci fi thriller direct by john dahl . a forensic expert ( ray liotta ) accuse of murder his wife inject himself with an experimental serum that may help identify her killer . use of flashback provide the meaty part of the movie . some scene be not only vivid and but stomach turn . liotta do well with the role and lead a very solid cast feature represent linda fiorentino and peter coyote and christopher mcdonald and kim cattrall and kim coates . fiorentino be my main interest in watch this worthwhile and a little far fetched mystery .
