The adventure of Melissa and Gustavo starts aboard a red cargo ship crossing the Atlantic Ocean. It takes them from Brazil to Berlin, a city of perpetual movement, where the old constantly has to give space to the new. The couple finds a home and transforms it into the center of their own universe. As time passes and seasons change, life and cinema become interchangeable and their apartment evolves into an ever-changing stage, where friends are invited to play their own roles and reality and fiction merge. Until one day a cosmic portal appears in their home, opening connections between the past, the present and the future.

Liz walks between different rooms of the city. A bar, a toilet, a wasteland, a garden, a trailer. The cruising body can't, unlike the flaneur, be alone. She won't leave the world outside of her. Several eyes follow her: the women holding the cameras, the director. The director is sending her a love letter. The director needs her cruising body. They are a part of each others fantasies and share a dream about a city's possibility of providing safe sexy spaces. They travel together to look for the rooms in between, to find rooms of their desires.

Doubt creeps in as Cosmo, a space traveller, addresses his gender identity. In need of clarity and change, he wants to risk crossing the Butterfly Nebula. His spaceship, on the other hand, has a personality of her own. Cosmo will need to negotiate change with a certain loss of control.
