[2] Struggling slacker Foster Sabatini is the only member of his circus family who left the life, greatly disappointing his wealthy father Max.

The arrival of the orangutans and Lazlo turn Foster's life upside-down, all while he attempts to win back his disgruntled girlfriend and impress her high-society mother.

Things are further complicated by a trio of bungling assassins hired by the local zoological society, which will inherit both the money and the orangutans if any of the apes die.

Once aware of the danger to the apes, Foster and his friends must save the newly accepted primates from the assassins.

The film was poorly reviewed by Janet Maslin of the New York Times, who called it a "completely unimaginative romp, standard to the point of being waxen" and referred to director Kronsberg's "messy directorial debut".
