From the adventures introduction:
This is a basic Shadowrun mission suitable for starting players to learn some of the rules or as a short emergency game for a more experienced group. The challenge level is scaled relatively low and is gauged towards the example characters in Shadowrun 4th edition. Scaling the power level should be relatively easy.
The plot consists of the players being hired to break into a corporate facility and retrieve a blood sample of an employee's wife before it is sent for testing at a medical laboratory and the fact that she is infected with the Kreiger strain HMHVV (the “ghoul” virus) is discovered. As cover, the characters are expected to damage certain items of equipment to conceal the true purpose of the break in.
