Miss Blandish (Linden Travers), a sheltered heiress, is targeted for a simple robbery by a cheap thug who ultimately involves two groups of rival gangsters, their goal being her diamond jewellery worth $100,000. The robbery is botched when Riley (Richard Nielson) kills her bridegroom and the three would-be robbers decide to kidnap Miss Blandish for ransom instead (her father is worth $100 million).
