Carl and Joseph Vernon are brothers. They are former physicists with NASA, now retired from the Space Center in Houston. They are genius, senile, bored, and missing the action of years spent in the Control Center.
The Vernon brothers, in their tedious lives, have come up with a hair-raising plan that they find truly exciting and have conjured up an idea that puts them back in action.
First element of the plan, the brothers walk out of the South Shore Manor Senior's Home, unsure that they will be returning.
Joseph, a septuagenarian, will take on the job of driving a refurbished city bus. But his frightful daily run provokes his commuters.
The scheme doesn't go as smoothly as intended, and obstacles fall into place, throwing things off track. Can the brothers pull off their plan? They intend to do exactly that.
All the while, police officers are hot on track to find the missing brothers, who are piling up misdemeanors and suspect of something menacing.
A backup strategy is necessary, and brother Carl steps up in an attempt to complete the plan.
Excitement peaks when the brothers come upon a discovery that blows them away. This is that one last fling they've waited for, for old time's sake.
A wild turning point occurs that translates into the brothers' restoring and retaining their self-acclaimed intelligence and all their achievements with dignity.
