Emma has it all. She's a successful lawyer with a loving husband, two wonderful children and a beautiful home.
Ryan is trying to build an elephant out of sand on the beach.
He was her first love; it ended badly many years ago and they haven't seen each other since...
It's awkward at first but they have one thing in common.
A strike has paralyzed public transport and they need to get to their homes: quite close, but on opposite sides of the river.
On their way they reminisce, argue, cry and laugh.
They can never recapture what they had, but the memory of it tempts them.
