Plot Summary

Lifelong friends Billy (Michael Douglas), Paddy (Robert De Niro), Archie (Morgan Freeman), and Sam (Kevin Kline) have shared decades of memories, rivalries, and unbreakable bonds. When the group’s most committed bachelor, Billy, finally proposes to his girlfriend after more than thirty years together, the four men decide it is time for one last unforgettable adventure.

Choosing Las Vegas for a bachelor party that defies their age, the friends head to the city of excess with the belief that they are still living in their golden years. Refusing to slow down or act their age, they plunge headfirst into nightlife, indulgence, and the reckless spirit of youth they refuse to let go.

However, once they arrive in Sin City, reality begins to set in. Las Vegas is no longer the place they remember, and neither are they the men they once were. Old resentments resurface, long-buried emotions come to light, and their friendship is pushed through trials none of them could have anticipated.

Blending heartfelt humor with reflections on aging, loyalty, and second chances, Last Vegas explores what it truly means to grow older without growing apart. As the weekend spirals out of control, the four friends must confront their past, accept change, and rediscover the value of friendship in a world that has moved on without them.
