Herbie (Robert Carradine) is set up to be the fall guy by his boss. Now in prison for fraud, he finds himself sharing a cell with the somewhat deranged Sly (Michael Winslow) and threatened by the various prison hard men including Cowboy (Roddy Piper). He is also abused by the Warden (Malcolm McDowell) who wants to use Herbie's skills to make himself rich...
Herbie's only way out is to use his skills in high finance and make the convicts rich. He also has a plan to bring down the Warden and his crooked former bosses...
This is a rather crazy film, the prison filled full of bizarre characters, sometimes a bit predictable. It is an enjoyable film with plenty of high points though at times it does veer over the thin line between zany into annoying. Michael Winslow reprises his sound effect gimmick from Police Academy though this treasure could have been made a lot more of.
