Dangerous remedy, a

Warden, the owner of a pharmaceutical company, determines to destroy the reputation of Nuala Collins, a successful manufacturer of herbal medicines. One of her products halts the onset of a common disease and is a growing threat to the sales of Warden's own drugs. Warden goes to unprecedented lengths to safeguard his own medicines: a jungle village where the healing plants grow is destroyed; the director of the scientific team is critically injured; and Nuala and Dan, her husband, are viciously targeted. They suspect that Warden is receiving police protection when, after the theft of private documents and a parcel bomb which injures Dan, the incidents are considered to be purely coincidental. Warden hires a contract killer to cover his tracks, but his arrogance endangers the hitman who follows Warden to Ecuador and resolves to kill him.
