the long version

"Rick Manton and Thelma Wain were two young people in love - but they were also grifters, who recognised no moral code and considered themselves above the law. And when mobster Dan Sweder moved to take over the drug traffic in Los Angeles, they found their own small dope dealing operation was being squeezed out. Rick and Thelma had only one answer: Dan Sweder has to die! So they set out to 'eliminate' him - two small-time crooks against the Mob!"--Publisher description.
