Billy (Michael Douglas), Paddy (Robert De Niro), Archie (Morgan Freeman)
and Sam (Kevin Kline) have been best friends since childhood.
So when
Billy, the group's sworn bachelor, finally proposes to his
thirty-something (of course) girlfriend, the four head to Las Vegas with
a plan to stop acting their age and relive their glory days.
However,
upon arriving, the four quickly realize that the decades have
transformed Sin City and tested their friendship in ways they never
imagined.
The Rat Pack may have once played the Sands and Cirque du
Soleil may now rule the Strip, but it's these four who are taking over
Vegas.
