The Middleman (2019)

Olivier is a homeless real estate agent so broke he camps out in the apartments he is supposed to be selling. The death of his mother brings along many surprises, including a very unexpected inheritance: a run-down building on the outskirts of Paris. Faith renewed, Olivier is going to be able to pay long overdue child support, rebuild his relationship with his daughter, help out his dad and square up with his ex-wife. His hopes die out when he sees the building: it is completely run down, filthy, a burden rather than the life raft he needed. An old woman, Liliane, is squatting the top floor, and he can't flip the place with her around. Trapped between blackmail, debts and threats, Olivier is struggling to keep a cool head. His only friend is the talking goldfish he saved form a near death, who turns out to be a trustworthy confidant and quite a droll character. As he gets legal consulting from his goldfish, he discovers that he can travel in time. Will he be able to change his past, and even more importantly, will his past be able to change the painfully intricate and lonely present he finds himself trapped in?
