It’s summer on Sway Lake, former playground of the jazz-age New York aristocracy. Young music collector Ollie Sway (Rory Culkin) recruits his only friend, a rowdy Russian drifter (Robert Sheehan), to help him steal a one-of-a-kind vintage record from his own family's glamorous lake house. Ollie believes that possessing the secret recording of the WW2-era hit, “Sway Lake,” will magically boost his confidence with women - and redeem his father, who committed suicide on the lake.
But the arrival of Ollie's beguiling grandmother, Charlie Sway, changes everything. The vision of the matriarch transfixes the young Russian - and Charlie has her own plans for the mysterious music, which hasn’t been heard in half a century. For this song may possess the answer to the deepest riddles about love, passion, death, and memory - for whichever lost soul is first to find it.
Featuring a sparkling soundtrack of classic songs - as well as the stunning original of the title - “The Song of Sway Lake” is a romantic drama about the vanished grace of America, and the spells cast by the melodies of lost time.
