Dave Ryerson is an international criminal with crime syndicate connections. He had been deported from the United States, which he blamed MacGyver for and according to MacGyver wasn’t even “meant to be in this hemisphere unless he was in jail”.
He had allied himself with General Antonio Vasquez, the military head of the secret police in San Sebastian, Central America, who was planning to overthrow the government. Vasquez had his army behind him but still needed the weapons, which Ryerson was dealing to provide for him.
He had planned a meeting with Vasquez to seal the deal, but the meeting was interrupted when photojournalist Kate Connally and MacGyver were caught taking photos of them. They were able to escape but Vasquez immediately put the country into military “lock down” to prevent them from leaving with their photographic evidence.
Ryerson was able to convince the General that they would be able to capture MacGyver and Kate as his army continued to search for the pair, but an unconvinced Vasquez promised Ryerson that if they escaped he wouldn’t depart him, he would instead destroy him.
Despite the military’s best efforts MacGyver and Kate were able to escape over the Mexican boarder with the photos and story, and Vasquez kept his promise to Ryerson.
