Rudderless

Divorced ad-exec Sam loses his son in a university shooting; at the wake at his ex-wife's house, he meets his son's significant other, Kate. Two years and many bottles of booze later, he lives on his yacht, works as a house painter, and meets up with his two workmates at a bar after work, keeping his past a secret. When his ex finally tracks him down to get his signature to sell their house, she leaves him their son's music things, including recordings of his own songs. Sam brings his guitar to the open mic night at the bar and sings his son's song. He gets his first fan, Quentin, who sees potential. Quentin manages to convince Sam to start a band/quartet, "Rudderless", to play "Sam's" songs.
