an oak tree is the story of two men brought together by loss: a father whose daughter has been killed in a car accident - and the driver of that car - a provincial stage hypnotist. The two are reunited for the first time since the accident when the hypnotist inadvertently calls him on stage as a volunteer. an oak tree is a remarkable new play for two actors. The Father, however, is played by a different actor - male or female - at each performance. The second actor walks on stage having neither seen nor read a word of the play they're in...until they're in it. an oak tree is a bold, moving and absurdly comic play about loss, suggestion and the power of the mind.
