Sergei and Marina have a crisis in family life. During one of the quarrels, they decide to go on an exotic journey. Quarrels do not cease all the way between the spouses, which ultimately lead to the fact that they find themselves on a desert island, lost in the ocean. Instead of fighting together for survival, our heroes continue to sort things out, gradually moving on to real hostilities. To top it off, the island appears to be inhabited by a tribe of militant natives.
