Voice From the Wilderness

Mark gets Tom to put a radio transmitter on Ben so he can hear what he's doing when he's away. After Ben wanders off a plane carrying exotic animals crashes in the bush. Ben runs across the plane and when Mark hears the moans of the co-pilot, he figures out where he is and goes to help him. Finding the plane and the injured pilot and co-pilot, Mark calls in the location with Ben's radio. One of the animals is a tiger, whose cage has broken open- Ben protects Mark and the co-pilot. Tom and Ellen then arrive in the jeep and tranquilize the tiger.
