Business is slow for Terry Leather, a London car dealer, married with children. He's an artful dodger, so Martine, a former model with a thing for him, brings him her scheme: a bank's alarm is off for a couple weeks, so let's tunnel into the vault.

A Trinidadian thug, a high-end bordello owner, and a pornographer also have things stored in the vault, so the break-in threatens many a powerful personage. Is there any way these amateurs can pull it off?—
