Dr. Bo Richards saves a woman's life in the emergency room at his hospital. She was a drug mule and forced to ingest a number of balloons filled with drugs to get them over the boarder to the U.S.

One of the balloons began to leak and the woman's life was at stake.

Later, Bo investigates the drugs in the hospital and in the area, He learns that the Surenos Mexican Mafia gang is running the drugs. They seem to have ties everywhere, in the hospital and at customs. If someone crosses to the U.S. and customs feels they need an xray, someone is there from the gang.

Bo is still getting over the death of his girlfriend who was killed in a hit and run accident a year ago. He meets a female police officer and learns that his officer was the last to see Bo's girlfriend, Cory, alive.
Bo and the police officer begin looking into the drug activity of the area together.

I enjoyed the story. How Bo succeeds and how the drug gang operates are interesting and eye opening things to observe. ( )
