16 new Houseguests move into the Big Brother house and will spend the summer competing for $500,000.

This season's first HOH, McCrae, must choose who he will nominate for eviction. Meanwhile, "showmances" begin to blossom in the Big Brother House, and Elissa's secret may be exposed.

Tensions rise in the Big Brother house as McCrae faces the backlash from the two Houseguests he nominated for eviction, and America chooses the first Big Brother MVP who also nominates a Houseguest for eviction. Also, the Houseguests compete for the Power of Veto which could change everything. Marcela Valladolid from the CBS show "The American Baking Competition" guest-stars.

The new HOH chooses two people for eviction and the house is divided between two big alliances.

It's the first live episode of the season and one of three House guests up for eviction will be sent packing.

Another houseguest is eliminated as the the remaining houseguests gear up for the next HoH competition.
