Six in the morning of a Friday like any other in Madrid. As usual, CARLOS (20) and DANI (22) have been out all night, at a club. As part of their particular party ritual on the weekends, they decide to go to a gay sauna to continue the party. Nevertheless, Carlos hasn't been feeling like himself for the past few weeks. He doesn't want to be there, and if he does end up going he does it reluctantly. Dani on the other hand is on his element, and this causes from the beginning, at the changing lockers, conflicts between them. Dani doesn't take long to pick on Carlos, stating that if he feels that uncomfortable, he can always call his dad to pick him up, as he usually does.

At this moment starts the journey of this Friday night at the after party. Dani and Carlos move around the different rooms of the sauna, the halls, the swimming pool, the cabins... Carlos anxiety keeps increasing by the second, for no apparent reason.

When they encounter PABLO (35), we see a generational clash between them, since the last one only occurs the saunas with a sexual meaning and in a solitary way, which is the opposite of what Carlos and Dani do. In the middle of the conversation, another persons name pops up, an older man who also attends the sauna, with the particular tendency to just stay still in the swing cabins. They call him ¨THE MAN OF THE SWING¨(52). Furthermore, Pablo offers some drugs to Dani and Carlos, in exchange of a threesome. Carlos anxiety catches up with him, and he exits the room, escaping from the situation. Later that night, Carlos and Dani end up alone. From that chaotic situation Dani took it as an opportunity to steal Pablos drugs, and proceeds to go on with his night happily until he notices Carlos is worried.

For the first time we see the two have a proper conversation with them not picking on each other, in which Carlos asks Dani what would happen if he stopped going to the sauna. Or worse, what if that was his last night attending the sauna. Dani avoids any type of intimate conversation.

Back at the cabins, the main characters encounter the man of the swing. They proceed to spy him, and start wondering what he might be thinking, or why he does what he does at the sauna, since he simply arrives and stays by the swing. Pablo interrupts the conversation harming Dani, in hopes to get his drugs back. After this Dani is comforted by Carlos. They both say goodbye, since Carlos says his dad must be about to pick him up. Finally, Dani meets Pablo and ends up practising oral sex with him at the time we discover that the Man of the swing is really Carlo's dad, who has been attending the sauna all along, being Carlos the one who goes to pick him up, and not the other way around, as it seemed throughout the night.
