Falcon Crest - Season 4 Episode 18

As Richard's first shipment of Francesca's wine is delivered for bottling, the truck is hijacked and the tanker is drained. Richard suspects both Chase and Cole, and after Richard and Chase fight, Chase concludes that the saboteur may be Riebmann and the cartel. He also details his suspicions that DeBercy may actually be Riebmann. Richard is surprised at the extent of Chase's knowledge about the cartel and so is Riebmann, who is listening from his surveillance room and realizes he must act quickly before his identity is revealed. He continues to use Emma to gather more useful information to further his plot. Meanwhile, Lorraine discovers that she is pregnant with Lance's baby. While Chase, Richard and Greg go to the authorities, Angela receives an invitation at gunpoint to visit Mr. Riebmann and his houseguest, Julia.
