What does the money mentioned on the phone at the end of Air Rescue mean?

In order to frame Bill, the ransom demanded by the hijackers was paid into Bill's account. Then they planned to blow up the plane. Except for the two robbers with parachutes, everyone else including Bill would do it. Death, Bill's trust account (opened by the robber) has been set up so that once the head of the household dies, the funds in the account will automatically be transferred to the accounts controlled by the robber, so that the robber gets the money, and The dead took the blame for them, but Bill didn't die in the end, so the huge ransom was still in Bill's account. This is the money you're talking about.
