Follow the adventures of Professor Ian Hood, Special Advisor to the government's Joint Sciences Committee, who troubleshoots threats stemming from or targeting "scientific endeavour". He is joined by Rachel Young, a Special Branch operative who acts primarily as his bodyguard, as Hood has made powerful enemies through his work.

Hood is on the trail of a doctor attempting to clone humans, and his only clues are burned or buried foetuses across Europe—the failed results.

The discovery of a barely living man in a crypt leads to a virus scare that's further complicated by another scientist's handling of the case, often in defiance of Hood's advice.

When Hood goes to meet an old associate, his deteriorating mental health puts in question his claims of sabotage, but the death of one of Adams' coworkers makes Hood suspicious and his investigation puts his and Rachel's lives at risk.

The seemingly miraculous cure of a boy's tumor from drinking spring water sends Hood on a mission to debunk the claim.
