On safari, Tom and Ted find a lioness that urgently needs treatment in their truck. To do this, Tom and Ted lower the treatment cabin of their truck to the ground. Now the lioness can be treated, as the truck is perfectly equipped for this: Ranger Tom always has bandages and a stethoscope on hand. After the treatment, the lioness is placed in the transport box. Using a crane, the cabin is first lifted back onto the truck, and then the box can be secured to the truck. Tom and Ted release the lioness at a large waterhole, where she can recover.
