The boys make it to the barge ramp with the wheel, and construct a junk raft in the hope of floating the wheel behind their inflatable dinghy.
Chico causes trouble at sea when he accidentally spears their dinghy, and the boys pile into the raft to head for shore with a need to survive and no supplies.
The boys are left without food or water as they continue pushing the tractor wheel towards the outstation, and race against time to find something to help.
