31 years after the first Bañeros, comes the fifth installment of the saga in which the spa is to be sold to new owners, unless the bañeros find a way to collect the money to pay what they owe and avoid losing their place of work.

The new bathers, together with a spectacular bathtub, will arrive in Mar del Plata with funny gags on the beach, ingenious inventions, innovative traps and imitations, and with the help of the marine animals from the Aquarium, they will face an evil businessman, in a spectacular and fun ending.
