As Kevin and Fede struggle to come up with the specifics of their science project, Kevin's older brother Leo is determined to interfere at every turn.

The power struggle between Kevin and Leo continues as their parents attempt to go out for the evening, leaving their sister in charge.

When Kevin's parents go out and his sister neglects her babysitting duties, the tension between Kevin and his brother, Leo, comes to a head over Kevin and Fede's science project. Will their hamster survive? Will Fede and Kevin?

As Leo begs his girlfriend to come over, Kevin is eager to wrap up his science experiment in spite of his partner Fede's reservations.

As Fede grows increasingly concerned for the health of Nico, the hamster at the center of his and Kevin's science project, Kevin's brother Leo's behavior becomes increasingly erratic.

In the wake of the hamster incident, Kevin and Leo's relationship is strained, to say the least.

Albeit tragic, the incident with the hamster has changed the dynamic between Kevin and his older brother Leo forever.
