Slither

S3 E22: On a world where California is part of Mexico, Quinn (Jerry O'Connell) and Rembrandt (Cleavant Derricks) take a "vacation" to Zamora. When they are bumped from their flight back, they luck onto a plane chartered by Kyra (Julie St. Claire). As they takeoff, a military Jeep chases them, shooting at the plane. In flight to Los Angeles (now called Delgado), Kyra tells them the crates she's transporting contain two poisonous tri-adders, whose venom will be used to cure diseases.
