Jason Kelly [Zac Efron] is one week away from marrying his boss’s uber-controlling daughter, putting him on the fast track for a partnership at the law firm. However, when the straight-laced Jason is tricked into driving his foul-mouthed grandfather, Dick [Robert De Niro], to Daytona for spring break, his pending nuptials are suddenly in jeopardy. Between riotous frat parties, bar fights, and an epic night of karaoke, Dick is on a quest to live his life to the fullest and bring Jason along for the ride. Ultimately, on the wildest journey of their lives, “dirty” Grandpa and his uptight grandson discover they can learn from one another and form the bond they never had.
After a nearly fatal accident, 21-year-old Lamb Mannerheim (Julianne Hough) is beginning to realize that the world is much bigger than her small, God-fearing Montana town. Armed with a big, fat insurance payout and a checklist of untried sins, there’s only one place for her first taste of temptation…Las Vegas! And, with the help of a few new friends (Russell Brand and Octavia Spencer), Lamb embarks on an oddball odyssey of lost souls, broken faith and cheap cocktails…a true journey of the heart.
