Set against Paris' oldest bridge, the Pont Neuf, while it was closed for repairs, this film is a love story between two young vagrants: Alex, a would be circus performer addicted to alcohol and sedatives and Michele, a painter driven to a life on the streets because of a failed relationship and an affliction which is slowly turning her blind.
A young man, whose only possession is a motorcycle, spends his time riding around the city looking for empty apartments. After finding one, he hangs out for a while, fixing himself something to eat, washing laundry or making small repairs in return. He always tries to leave before the owners get back but in one ostensibly empty mansion he meets the abused wife of a rich man and she escapes with him.
