Friday Foster, a magazine photographer, goes to Los Angeles International airport to photograph the arrival of Blake Tarr, the richest black man in America. Three men attempt to assassinate Tarr. Foster photographs the melee and is plunged into a web of conspiracy involving the murder of her childhood friend, a US senator, and a shadowy plan called "Black Widow".

When a rich man dies, some items from a collection of his are stolen- an ancient Egyptian gold amulet and the mummy that was wearing it. The police consult scholars from the local University to help with the investigation, which is taking a more serious turn as people connected with the case are killed by wounds that seem to be from a housecat.
