Stylishly directed chase film from Lewis who had previously shown his talent in GUN CRAZY. Gassman plays a reed-hopping fugitive who is closely trailed by Sullivan through Louisiana's swamplands. The location, which is strikingly photographed, adds to the gritty sweatiness of the pursuit.
While being transported to a courthouse to play informer, Gassman makes his move and escapes. At one point he is caught but again breaks free, only to be recaptured again at the finale. Interesting subplot has Conrad waiting for Sullivan to make a wrong move so he can grab his job.
