Always-dutiful young lawyer Jason Kelly (Zac Efron) thought he was doing the right thing when he agreed to drive his newly widowed grandfather, retired soldier Dick (Robert de Niro), down to his Florida property. Trouble is, the long-sexually frustrated oldster is just itching to cut loose... and he starts dragging his helpless grandson into a riotous road trip of spring break debauchery! Gloriously inappropriate farce also stars Aubrey Plaza, Zoey Deutch, Julianne Hough, Dermot Mulroney, and Danny Glover. 121 min.
